Topic  3998  Increase The FPS Simulation For Retiming
Hello everyone, I'm trying to slow down my particle flow simulation. This was the information I could get from the FAQ regarding time: Quote: Parameters that measure time in Particle Flow, such as Birth Emit Start/Stop and Age Test Test Value, are specified in frames. However, Particle Flow is always aware of the current system frame rate (fps), and if you change this rate, it adjusts all time-related parameters to keep the same timing. For instance, if you set Test Value to 60 when you're using the NTSC frame rate (30 fps), and then switch to PAL (25 fps), Particle Flow automatically changes the value to 50, so the age that's tested for is still two seconds. On the other hand, rate parameters, such as Speed, are measured in units per second, so they don't change when you go to a different frame rate. I already researched how I could slow down my simulation but the solution that I could get was defining the final look of the particle behaviour in 30 FPS, then I increased to the desired FPS, in this case 240, and adapt some of the parameters that don't change. This process takes a lot of time so I was trying to speed things a little bit. Is there a way to store the data in cache like fumefx and then do a retiming? I'm checking these two links now, one that uses the PRT Loader for retiming and the other that talks about bullet time - http://www.thinkboxsoftware.com/kra...rt-anim-prtldr/ http://www.orbaz.com/forum/viewtopic.php?t=175 Just wanted to know the opinion of the community about this. Thanks. Cheers

Topic  3997  Changinq Spin Pivot
Hi everyone! Its pieces from a asteroid "explosion" I have a Shape instance with "Separate particle for: Group Members" They are using to Position and Spin, the pivot in center of Group. When he breaks in colission, After Age 1, I want use to Spin the pivot in Center Of Each element of the group. To spin correctly. But he is using the pivot of center of group SomeOne know how change the pivot used to "Spin" ? I changed "Spin Axis" to particle space, when is only a one particle alright, but in this case with pieces of the group, dont work. Could be also Use the Group pivot to Initial position, and the pieces pivot to Spin, but Idont know how do this.. Here de animation test, after asteroid break you can see the pieces spining in wrong axis: https://www.youtube.com/watch?v=oprWoisJL28 Here what I want: https://www.youtube.com/watch?v=np6mEfRB1wo But with the several pieces.. Someone know how? Best regards! Ricardo Mendes(Ricmage)

Topic  3925  Spawn Test Question
Hey PFlow-User, at the moment I got an animated sphere, wich got particles in the volume of it. These particles (20) emitting particles with an spawn test per travel distance (See the Screenshot"PFlow") and the speed of the sphere is inherited by the particles! But now the particles spawn in groups (like you can see in the picture "Particles") and when I increase the "Step Size" in the "Spawn"- test the clouds just getting more dense. How can I fix it, so that I can get particles everywhere? I hope you got eneough Information, Thank you!!! Dewey PS: Subframe Sampling in the "Birth" and "Position Object" - Operator is checked!

Topic  3909  Stacking particles/rebuild surface with stacked Particles
Hello everybody i`m new to this forum and new to pflow although. I search for some advice how to rebuild a surface with stacked coins. I tried with mparticles but can`t make it work. So I ended up with 4simple pflow systems . My surface as object emitter and a little bit offset and a new seed with every system, to create the illusion the surface is made of coins. But i´m not satisfied. The coins are floating and sometimes intersecting. I try to find a solution that will work even with a closeup. Is this possible with pflow in max 2014? And is it possible even for a newbie? :? [url=http://postimg.org/image/vtit9x27d/][img]http://s12.postimg.org/vtit9x27d/STack_coins_test.jpg[/img][/url]

Topic  3888  disassemble and reassemble particle shape

Topic  3887  animated shape instance -playback speed control.
apologies as this might have been asked about before.. i didnt find anything in a search. i have a classic scene, butterflies flapping around. i need them all to start animating as they are born, as they start with a "taking off" motion, then continue in a manually keyframed flying sequence. they also have a pointcache on the wings for the flexing. problem is i need much more randomness, they all flap at exactly the same speed, and it bears no relation to their behaviour as particles. im after the ability to control the playback rate of the animation, and vary it randomly, but also, ideally by other factors, such as the particle velocity or direction. if i had that control, it would be easy to have them slow to a glide as they descend, and flap like crazy when they go fast. is this possible? is it a box3 thing? thanks for any assistance, greatly appreciated.

Topic  3883  Painting a texture using particles ?
Does anyone know of a way to paint particles onto a plane by using particles ? Basically everytime a particle hits the plane that area gets turned from black to white ? I was thinking vertex paint would probably work here but I'm not sure how to get that modifier to communicate with the particles.

Topic  3880  how to destroy and rebuild (morpher effect)?
Hi guys...just saw a short video and was wondering how the guy did that: http://www.youtube.com/watch?v=ve18786TL8o To destroy the teapot I would guess he just fractures it and then uses the birth group with some physics...but then he manages to send those particles to its original source while that one is actually moving.... How would you do that? Using data operator trying to record the position and rotations of the original particles and send that back to the second event? Im a bit lost there... Thanks for any help! Cheers :roll:

Topic  3858  pf cache to vray proxy
Hi, I'm working on a few shots where I have trouble rendering the pflow system with mblur cause of to less ram in our farm. Now I have the idea to write the system as vray proxy to get it hopefully rendered with mblur. But, I cant get it written directly to the vrayproxy. I currently use the workaround to xmesh it first than convert it to a proxy. And it seems to work smooth. But there must be a way to convert it directly or? May anyone know?!

Topic  3817  Particle Age/Speed not working with FumeFX Follow
Hi all, I am fairly new to 3ds Max, though have been working with 3d programs for years... Recently my studio adopted a 3ds max/fumeFX/krakatoa workflow for effects. Everything is working as planned, except for being able to control any particle age/Speed through the mapping object+material dynamic operators. I've read through countless forums to find a solution and as my understanding of PFlow and Max is not deep enough to find any results, I fear it may be a bug. So Im hoping any one out there can help and shed some light on the issue... I'll attach a scene file of what I have set up at the moment.... basically its a FumeFX sim, Pflow generating particles on the FumeFX birth and Follow... Ive added Mapping object + Material Dynamic in the event, with a delete operator. Inside the Material Dynamic I have a material assigned to it, bercon maps in the diffuse... the maps work perfectly with the Normal channel, but nothing in Particle Age/Speed? Many thanks in advance.. Brett

Topic  3806  Emit Forces or Emitters
Hi! Thanx for the really interesting forum, first post here. Does anybody know if there's a way of emit forces? I mean, instance forces instead of geometry? I tried to find the way but it seems not only imposible but also i haven't found any similar references on google or this forum... Nobody tried that before? can anyone help? And also. in the same kind of question. It seems impossible also to emit a particle emitter...any clues? Thanx in advance!

Topic  3736  Particles disappear in viewport if anything is adjusted
Hello, Just started using PFlow a couple weeks ago. I'm running into this problem which is a huge pain correcting with the only way I've discovered so far. Whenever I adjust anything in my PFlow or scene (object size, orientation, etc) the particles disappear. I then have to turn the light bulb off/on of the PFlow source, then they come back. Which prevents me from seeing real time updates. I have a 6 core, 64 gb of ram, running on the Nitrous driver. Particle count and update progress are both off. I'm emitting a tiny amount of particles, less than 300. Any ideas what's going on? Thanks, Nathan

Topic  3712  A tablet dissolving in a glass of water.
I have created a scene with glass and filled with particles. Now a tablet drops inside the glass and enters through the particle vigourously to the bottom of glass. What I want here is disslolving effects. And the situations like; 1. When the tablet touches the surface of water, water jumps 2. It goes inside the water with turbulance, little disintegration and bubbles. 3. When it strikes the bottom of glass, it starts melting 4. And the melting partilcles dissolve in the water with its white color 5. The outcome water should be little whity due to dissolves tablet. I tried out glue 3d, thinking particles, and tools ox 2 and 3 an partilce flow. thanks in advance.

Topic  3543  position object density by material issue
hello, played some time with position object operator and its density by material function. here some questions: could it be: 1. that vray materials are generally (as density source) not supported? 2. camera map per pixel (as density source in diffuse slot in standard material) isn't supported? 3. ink 'n paint material (as density source) isn't supported? would be neseccarry to get it all work or to get a workaround (some box3 advantages?)

Topic  3492  viewport extremely slow with max 2011
so i'm trying the demo of box#3 on my 3ds max 2011 64bit and i can't make it work properly, my viewport is extremely slow and there are not even so many particles in the scene. It takes over 2 minutes to update the scene at any change, and if i increase the number of particles it can take over 2 hours to get nowhere. I'm using OpenGL, but there's no big difference with directx 9 or 10. I read on a forum that pflow is not desisgned to work on machines with AMD cpu and ATI gpu, is that true? No particles for me on this machine? these are my specs: CPU: AMD Phenom II x4 3.2 ghz GPU: Sapphire 5770 HD 1gb ram: 4 gbs ddr3 OS: win7 64 bit

Topic  3474  particle paint dropped when reopening project file
Hi all I've been looking to see if this is a known bug and how to resolve it but can't find any info. I'm using particle paint helper to store vector points in a script operator and then using these co-ordinates to send particles to a find target operator downstream. This works fine. However, every time I close max and then reopen the file the placement paint operator has lost the particle Paint Helper. It has done this in 2 different projects, with different set ups I did to test the problem, so it seems a consistent problem. I want to use backburner to render this scene which isn't possible as the particle paint info is missing. Anyone else had this issue? A possible solution I would think is to somehow permanently store the vector info generated in the particle paint helper and then use that instead of the paint helper. I'm new to all this though and don't know how to script this. Any help would be greatly appreciated.

Topic  3398  match particle effect with pflow
I have a reference for a particle effect I need to duplicate.. I'm not sure if I need extra orbaz boxes or not. The effect has a particle stream that has particles traveling forward and backward along a spline/path, as if they are carrying information back and forth... There are larger foreground particles and smaller denser background particles.. Behind the particle stream is a wispy cloud-like layer, very ethereal .. My attempt to match it was maybe 50% there.. A particle sprite was provided, but I couldn't get the particles behavior correct.. I was using age tests and find target operators to have the particle stream around characters.. I was told the original particles were created in a propriety script/plugin for Maya.. I can post a video reference when I get home, i would really like to match this closely.

Topic  3382  noob seeks advice...
Hiya to all, Im fairly (but not completely) new to particles. I dont own the Orbaz plugins but have a budget for them should this project require. I need to do a stylized 'impact wave' traveling the length of a car. Not a car wreck, more of a transition technique to change the car options (paint color etc). Im thinking of a cubic wave form that travels the surface of the metal. Kind of a Mexican wave of cubes. Any ideas?

Topic  3369  controll of position
is there a simple/ known way to manipulate directly the position instead of speed of particles? want to use as most as possible of pflow box 1 inbuilt features. scripting would be okay. but should not cut the flexibility of standard operators. what i want is to controll particles by audio float controller (indirectly over an animated parameter of an object: e.g. the height of a box). if audio input is zero the particles should be in start position. if audio level is at 100 % particles should be at target position. and all other audio values should set the particles to corresponding positions between start and target position.

Topic  3321  updating at render time
Hi everyone, so basically i got this really simple project that just cant seem to finish due to lot of technical problems due i think to PF and probably my lack of understanding of it i guess. I got many water jets coming out of the ground. There is 9 events wich gives birth in the source. All instanced stuff except the position and speed by surface so the particles emmit from different emmiters. (hope its clear :P ) 20 000 particles (wich is not enough for the effect but its too long to update at render time!!!! :( ) for each birth, then when they collide they spawn like 3 childs for 75% of them. There's also a keep apart in there and a speed by surface. Hmm so i mesh them with Vray bercon metaballs at render time. But when i send the job to backburner after 30 frames or so it hang and it wont render anymore. Have to cancel everything restart everything then throw it again for 5 frames..then again.. Its such a simple scene dont understand why its so hard to get the job done, so if someone can give me some hints maybe it'll be great dont know what to do anymore. Also if you know how to get a velocity pass from the bercon metaballs that would be great cuz i tried everything but with no luck... Thx a lot. Jay.

Topic  3159  birth group issue
Hi i want to create a birth group with chunks from a prefractured object and then send out to a new event using a deflector, the problem is they all get send out at once when the deflector passes the pivot of the original unfractured object, although i did center the pivots to each indivual chunk before adding to the birth group i guess this is more a max issue, when i do "Reset Pivot" the pivot resets back to the original pivot of the unfractured object for all the chunks, maybe someone of you knows a script how to completly delete the original pivot so that pflow looks at the current one ? or maybe another workaround ?

Topic  3128  Cell Mitosis with Pflow help
Hi all, I'm working on a way to animate Cell Mitosis using pflow. So far I have looked at Pete Drapers Tutorial (can be found here: http://www.computerarts.co.uk/about_us/latest_issue/stop_press if your looking for it.) It is very good but is just not what I'm trying to do. I have animated a sphere that splits in two and with Pete Drapers pflow I can get it to spawn in different ways but it is not effect am looking for, it is too random. This is effect I want: http://www.youtube.com/watch?v=QrMo...feature=related and hopefully lead to this: http://www.youtube.com/watch?v=m73i1Zk8EA0 I want a particle to spawn into 2 particles and then from the nucleus of both particles I want to spawn 2 more again and again and again and so on.

Topic  3125  Lock/Bond in hierarchy
Hi I have a single particle (Particle1) moving through another PFlow system picking up the smaller particles with Collision and Lock/Bond. Then I have a final separate particle (Particle2) bump into Particle1 and ideally carry it plus all the Lock/Bonded small particles along, again using Collision and Lock/Bond. But I can only get Particle1 to Lock/Bond with the final particle - the smaller particles Lock/Bonded to the Particle1 don't follow Particle2's movement. Is it possible to have the smaller particles remaining sticking to Particle1 after it is hit by Particle2? I've tried playing round with Groups with no success. Thanks Mark

Topic  3103  How do I target objects from Emitters activated over time
I have a similar problem like the previous guy. I also like to target objects. But actually my problem is: how to set for e.g. 2000 particles exclusively one one single emitter but this for every emitter when the emitters will be activated (collision test of proxy particles) over time (no distributed particles caused by setting all emitter meshes at once as emitters in the [b]Position Object[/b] Operator!!!)? In my case in the end I will have to manage thousands of find target operations - so I need a flow based on particle age of my proxy particles. I want to populate my thousands of emitters over time and also only for a specific duration (in the best case for only one frame). So my precise question would be: is it possible to script the emitter objects in the [b]Position Object[/b] operator over time? Let's say $Box01 should be the emitter at frame 0, $Box02 at frame 20, $Box03 at frame 40 and so on. I tried this within a [b]Script Operator[/b] after [b]Position Object[/b] operator, but it updates only when clicking on the [b]Position Object[/b] operator in [b]Particle View[/b].

I understand this as an ease in for the docking part of the movement. But where can I say "ease out" for the starting part of the movement? Actually I'm dissatisfied with my particle motion because it is'nt soft.

Topic  3037  falloff distribution of PFlow
Please look at the attached file (2010). The particles are distributed throughout Sphere001 using a Falloff map with an adjusted Mix Curve. The number drops off towards the edge of the sphere. It's working fine. Now, in PFlow delete Sphere001 and choose Sphere002 as the position object. The mesh and the material are the same, but the particles aren't distributed properly. They fill the sphere evenly. It looks like this setup only works if the position object is at the origin. I've tried using a 3D gradient map also, but get the same results. Is this a shortcoming in particle flow? Any way I can get round it? Thanks Mark

Topic  2697  [HELP] Dynamic shape instancer (with script) ?
Hello, could someone help me fix this script? I think it's pretty handy... it's supposed to help you dynamically create any mesh shape and assign it to any particle. In this way it's easy to render complex shapes in a particle system, even if the required shapes have different materials. The idea is very basic: for each particle it creates a snapshot of a template mesh and then applies a TM to the created mesh to match the TM of the particle. To keep track of the particles that have already a mesh assigned Im using a global array. PROBLEMS: - (major) it simulated fine in the viewport and when rendered as a single frame but it doesnt render correctly when rendered as a sequence (in the render you only see one mesh, while in the viewport you see the simulation correctly) - sometimes the reset/cleaning functions don't work properly and have to manually delete the instances created.

Hello I´m making a crowd simulation and have one problem: [b]The particles are spinning around from "Keep Apart" in place of keep their faces to forward.[/b] [url=http://www.postimage.org/image.php?v=gxIrJ6J][img]http://s1.postimage.org/IrJ6J.jpg[/img][/url] For moving particles, I use "Find Target", where these particles have shapes of the animated mesh objects. For keeping their faces forward, I have "Rotation" operator with "Speed Space Follow" instead of it - and all goes just fine, but when they have to pass through the door of a building, they start accumulate and while they´re waiting for their turn to pass, all of them are spinning around. For keeping them apart there is "Keep Apart" operator too in the scene which makes them turn and go back when facing each other. I can´t change the value of "Rotation" to any other modes, because all of particles are going from the different points to the door, and they must change their directions very often. How can I fix this? If it is posible to make them any restrictions for no allow to turning back or somthing like this? Will be excelent, if there will be any way to make them stop, wait for their turn, then go forward a little bit, then wait again and so on... How people make it when exiting from the building.

Topic  2570  Find Target and Animated Radial Material
Allo all. First post here, but I float around CGtalk under the same name. Nice to meet you all in advance :) So I have a client thats asking for particles to swirl in from the outer edge of the camera, spin for a bit, then reveal their logo. The logo reveal is supposed to happen even as some particles continue to swirl in the center (rolling age test ofcourse). My initial idea is to use an animated radial gradient ramp, but at the moment the method I have (Event 1 Find Target to Event 2 Position Object) involves popping particles to that position, which loses all movement that the particles had gathered. I know there has to be a better way, so while I continue to RnD I wonder if anyone here has an idea? Cheers for any responses in advance. Brad

Topic  2359  cache operator not working after reloading scene
I added a cache operator to the global event to cache a pflow consisting of several events, something I have done for years, never a problem. After caching the frames manually (let's say frames 300 to 500) and try to render locally everything works fine. If I disable the cache operator and spend quite some time watching percentages everything fine, too. If I send the scene to backburner or save and reload instead, no particles show up at the respective frames. I tried to repair the cache operator/system the way described here in the forums. Nothing changed. I use three other pflows in the same scene. They all work fine (caching). I use Max2010, latest patches and connectivity extension installed. Anyone experienced anything like that before? Or knows why it might happen? I already lost 2 days of work (partially while rebuilding the whole pflow which did not help either), any ideas are appreciated. *edit Is it possible, that particles somehow change material ids, which where defined in the global event, while going to another event? This might be a possible reason

When I do this, the shape instances seem to loose the ability to be animated (ie I'm using a point cached animated object as the shape instance). Should I place the shape instance into only the original event (along with the birth operator), and only have another shape instance for the event that I want pflow to use a different object, or should I place the shape instance operator in the global event?

Hi In the attached file, how can I make the spawned particles centre on the main particle and travel along with it?

Topic  1787  PFlow Advanced in Max 2009
[quote]We've been working with Oleg, the creator of Particle Flow, for almost a year now, and he's brought some of his wonderful tools to 3ds Max. While this might appear to be Box1, it's actually something else as Oleg has been deep in our code and fixing problems and performing a much better integration. The result: faster performance, cleaner UI and full Box1 backwards compatibility. While much on the surface stays the same, there are a few things that have been much better integrated and performance and memory management are two of these.[/quote] [quote]Advanced Particle Effects Incorporate sophisticated particle effects into your scenes. PFlowAdvanced includes 12 operators new to 3ds Max Design, giving you easier access to a whole new range of creative options. The addition of the PFlowAdvanced technology to 3ds Max not only greatly enhances the functionality of Particle Flow, but it also gives you a high-performance, streamlined 3ds Max workflow, through which to access its features. - Numerous paint tools enable you to precisely place particles in your scene. Operators—including Particle Paint, Birth Paint, Placement Paint, Birth Texture, and Mapping Object—enable you to paint both particles and emitters onto specific parts of your objects. Other special effects include the ability to emit particles based on animated color data in emitter objects. - The utility operators have been integrated into the 3ds Max core to extend Particle Flow's capabilities, while giving you a streamlined workflow for creating particle effects. Clean up particle flow, synchronize layers, repair the cache system, save a custom flow as a preset, and automatically delete operators that are not in use and lock or bond particles to an object (improves on the former position object operator). - The ability to group particles enables you to perform specific operations on arbitrary subsets of particles. Quickly create multiple groups and work with as many of them as you like through such operators as Group Selection, Group, and Split Group - The PFlowAdvanced Shape operators greatly expand the Particle Flow Shape toolset. Define a particle shape beginning with a pre-existing shape—a vast range of 3D and 2D shape presets are available to choose from. Additionally, the Fast Shape Evaluation operation evaluates a reference mesh object on the final frame quickly and accurately, significantly improving performance. - Workflow enhancements include an Express Save operator that has been integrated with the 3ds Max auto-save functionality, backward compatibility with Orbaz Particle Flow Tools, Box # 1-based scenes, and general memory and performance improvements based on source code optimizations.[/quote] This is great news. Anything you want to say about it, Oleg?

Topic  1701  PFlow to Reactor and vice versa
Hi, I was wondering whether this is possible - I'll be interested in hearing all possible options to achieve this. I have a character that is comprised of different objects. At some point the character gets hit and the objects break apart, fall on the ground, and later assemble again to the character. These are big objects, not tiny sand-like particles. I can disassemble the character and re-assemble him using the good ol' Allan McKay method (sphere to teapot) - 'a la Sandblaster'. However - I don't necessarily want the particles to flow from one state to another - I want them to fall down naturally on the ground and be properly affected by gravity and dynamics. The problem with instanced shapes, though, is that they penetrate through the floor and into each other - which is why I'd rather opt for Reactor - which uses a cage as boundaries for the segments. SO here's the question - is there a way, and if so - how, to switch between PFlow and Reactor - and in such a way that at the time of the switch - they inherit each other's velocity? Alternatively - is there a way to prevent particles from penetrating everything, especially when using instanced shapes? Thanks a bunch.

Topic  1672  Stop gradually and vortex don't appear to work together
Hello, I started the same topic in CGTalk, so sorry if people have already read it there! I've got a vortex with no radial pull, which is just making particles go round in a vertical circular tube. I'm trying to make them stop gradually as they orbit around the center of the vortex using the Orbaz Stop Gradually operator, however it doesn't seem to want to play ball with the Orbital Speed of the vortex. The easing is so tiny that the end result is either moving particles, or s fairly sudden (over 2 frames) stop, rather than a nice gradual slowdown over 50 frames, or whatever. I've included a picture here where I traced out the particle trajectory to a spline: [url]http://forums.cgsociety.org/showthread.php?f=206&t=616596#post5062434[/url] Has anyone come across this before and has a solution? If not, I'm probably going to script a solution (unless anyone has a better idea!?). It would be interesting to know how Stop Gradually works internally, so I don't follow the same route, which may also not work. Thanks! Dave

Topic  1671  Collision Mesh
Hey Guys, Im having very annoying problems with pflow and collisions. I have a pretty simple setup. Particles emitting off a noisemap and selected faces. Gravity, drag wind etc and im also using the same mesh in a UDeflector and trying to get the particles to collide and bounce off. The mesh is pretty huge and had turbosmooth and displacement on it. The mesh im using was pointcached to begin with, then I ended up trying the skinned mesh, but nothing I do seems to make it collide properly. It will collide for the first 100 frames then stop or just not do it at all!! I have tried using a simple sphere as a deflector and that one seems to work fine, and have also tried changing the integration steps and recording the point cache at 0.2 sample rate. Im using Max9 and have box1 installed too. Any ideas?

Hey, Looking for suggestions on the best way to pour particles out of a bag and have they collide with one another and, for lack of a better term, "mound up" when they collide with the ground.

I've got the basics of the system build...the pour and the collide...it's the mound that i'm having a hard time with. thanks -b

Topic  1596  Motion Inheritance
I have an issue with a scene where I want to make a sparkler effect and it looks good if the emitter is stationary. The trouble comes when I constrain the emitter to a path and some of the particles get left behind. I know this is to be expected as now the emitter is moving so the particles would indeed be left behind as a trail. What I am wondering; is it possible to have the emitter linked to a path and not have its animation effect the speed of the particles? Here are some images to illustrate my question Image01 - emitter not constrained to path [img]http://www.intrinsia.net/transfers/ui_01.jpg[/img] Image02 - emitter linked to a dummy which has been constrained to the path. [img]http://www.intrinsia.net/transfers/ui_02.jpg[/img] So essentially I am looking to take the look of the stationary emitter but have it move along a path. As you can see once it has been linked to the dummy I get the 'comet trail' look. I can increase the speed of the particles but it still doesn't give me exactly what I need. Is there a way to have the particles emit relative to the position of the emitter or am I stuck to using some other method? Thanks in advance.

Topic  1580  flipping array of goodness
So here is our dilemma. We are creating a grid array of instanced boxes all with mixed shaders. These boxes need to sit dormant for about five seconds then randomly rotate on X 180 degrees. In mid flip these boxes shaders change all to the same shader. Picture an array of red, white, and green boxes. After five seconds they all flip in X (at random times or perhaps a collision test) and become blue boxes. Using Bobo's object vertex birth script, we've been able to get the array working and most of it close. We don't currently own Orbaz Box #3 and cannot find the Position Object+ operator for Max2008. The trouble we run into is making the switch from the dormant boxes to the ones that rotate in X. After the age test, the second instance operator changes where the particles sit and causes a pop in their shaders. Any help would be greatly appreciated. -chad

Hi Folks. I know this topic has come up in the past,- but I've only been able to find a broken link to the solution :( I have 5 pflow systems attached to vertices of animated planes (position object).

Over 200 frames, I get perfect motion blur for 70-80 frames or so, then the blur is "abandoned" all together for the remaining frames. Is this caused by sub-frame samplings? Object property settings? Pflow settings? Not quite an expert at pflow, using Max9 and vray 1.5.4 Thanks for your input, Kind regards, Mike

Does any one know if it is possible to use a keep apart operator to affect only one axis? I am creating a traffic sim and i need the cars to travel down a spline (using speed by icon) with a random speed variation. however this causes the cars to intersect. By using a keep apart operator i can make them avoid collisions, but the particles then ignore the speed by icon and go under the road or up into the sky.

The problem i have is that, even with turning off all values of my deflector, it still pushes the particles out of their original emplacement... and obviously, for my puropse, i would like to avoid that and keep them orderly placed. Any suggestions? :D So i know it's not directly related to the Orbaz Tollboxes, but since i just purchased Toolbox1, i figured maybe there is a simple way around it with it, in any case, thanks, any help would be welcome! I've put a max 8Sp3 + toolbox1 file on line here : http:perso.orange.fr/zanetti/Particles_Tiles_Growing.zip Pe@ce Adriano

Topic  1505  Particle collision when object is Skined...
Hi all, I'm having a problem which I overheard could be corrected with one of the tools (Box#1 or Box #3) but I cant pinpoint which specific tool I could rectify the problem with. My problem is this: I have an object that deflect the particles with udeflector (even other deflectors brings the problem) + the particles are under the influence of a vortex...till now everything works perfectly well...but, the object on which the particles deflect (actually the particles glide on this object so they constantly have to deflect...not just once...) so the object is Skined, and is kind of alive if you will, so when the object moves and deforms, the particles stop to be deflected and goes through! So I overheard that its a problem with the deflectors who in this case does not calculate all the way but onle once, or something like that...anyway, it's definetly a problem that should not exist so is there a tool / add-on that would actually rectify this? (or is it just me who does not setup my stuff correctly?) I'm only using the native tools that comes with Max 8, that is PF with udeflectors and vortex...no added plugins ... Thanx a bunch in advance for any help on this, Stef

Topic  1504  5,060470 faces the render limit for Pflow?
Posted this over on the area but thought i'd post here also: Seem to of hit a bottleneck with the amount of faces that Pflow can pass at render time. Whether using scanline or finalRender the maximum amount of faces seems to be around the 5 million mark. This must have been encountered before, can anyone else confirm? 1st came across this in version 9 64bit. Haven’t moved over to 2008 as mid production but thought i’d try it with the core improvements and that but still same bottle neck. This is not about the max amount of particles, it is just about the resulting face count. The viewport actually appears to show all the particles but when you render particles disappear. Have just tested a 10 million face scene with just instanced spheres, no Pflow involved and it renders out fine so the weak link is definitely Pflow.

Topic  1489  lock particles to objects to detect collision
Hi, I'm pretty new to pflow and I'm trying to setup a system to detect whenever an object (which is hand animated), is colliding with a deflector. fx whenever an object hits the water, some particles spawn from that possition. or like when a character's feet hits the ground, some dust spawns. I've got the particles to spawn and lock to the possition of the dummy objects, but when the particles hit the deflector nothing happens. They don't go to the next event. If I animate the deflector to go through the particles it works, but that's not what I want. Does anyone know how to do this properly? I have included the the scene below: [url]http://www.jbdesign.dk/dump/locktest.rar[/url] Any help would be great :) Thanks, regards, Jacob Børsting

Topic  1484  particle view 01 bug
Hey All, I found a bug and thought I would share it along with a solution. This may already be known, but I figured I would share it in case others run into the same thing. To create the problem: - I created independent max files containing different particle flows. - Merge the files into a new max file It seems that multiple particle views can be created with the same name which can render your particle flows invisible in the PF view. To fix: - I opened the maxscript listener and "select $particle*", when I print $ I got: $Particle_View:Particle View 01 @ [0.000000,0.000000,0.000000] $Particle_View:Particle View 03 @ [0.000000,0.000000,0.000000] $Particle_View:Particle View 02 @ [4.958793,3.561117,8.568209] When I deleted particle view 01 and 03 my PF view populated back with the particle flows again. I'm unsure if you are only allowed one particle view -- but it seemed to conflict somehow. I'm sure someone else understands what is going on there -- but thought I would share the solution that ended up working for me. J.

Topic  1482  Possible to stop PF from orphaning particles?
Another day, another question :) I have some fire that is on a stick and it burns nicely. It actually licks upwards and spews some smoke. Everything looks nice. The problem I have is that when the stick is animated the particles are left behind. While there is some 'realism' to this, I would like the particles to act as though they are their own system and will always: Create a licking flame w/ smoke that holds together as though its PF source was not moving. In other words, I would like to make something like a flow of particles that would move around as though it were like a lightsaber. A solid grouping that is attached rather than orphaned off. Thanks, j. [url=http://www.postimage.org/image.php?v=aVmnxK0][img]http://www.postimage.org/aVmnxK0.jpg[/img][/url]

Topic  1481  scaling a PF
Hello again (hello Oleg :), I seem to have a lot of questions lately -- let me know if it is getting annoying :). Can PF setups be reused for other scenes that have a different scale. For example, I have a PF that was built too large. I've tried scaling it down, but obviously all the variables are not scaled along. For example, the distance the particles are traveling have not scaled along with the particle size. I'm assuming this is either as problematic as it is trying to scale bones or there might be a tool of some sort that takes care of this? Jason

Topic  1480  controlling draw order when using facing particles
Hello all, :) I don't have access to plugins and need to generate some fire effects fairly quickly. In that regard I have decided upon using 2D facing particles to create fire. I have set this up using one render node and several births that render out facing geometry for smoke, embers, flames, and a brightness flicker During the playback however, the draw order seems to be random. At times the flames are in front while in others they head to the back. Is there a way to explicitly state the draw order for the particles in a single render? Thanks in advance, Jason

Topic  1392  Problem with Velocity channel and Pflow??
Hello peeps! I'm having a spot of bother with my render. I'm animating some facing sprites using Pflow in Max 9. The particles are moving from right to left in the scene while the camera has some slight noise to simulate camera shake. The camera position is unchanging. I'm rendering out a 64-bit velocity image with Vray 1.5 and using a trial version of RSMB in AE to comp the motion blur in post. For some reason, the motion blur is not rendering correctly with RSMB.

Topic  1180  Density by Material problem
Hi, I am on MAX 9 and I am trying to achieve a dispersion effect by using a position object operator. I have a gradient ramp map with a small white strip in the middle indicating where the particles should be emitted. If I put this material on an object everything works fine. But I want the "emitting area" to wander over the object. When animating the white strip in the gradient ramp, everything works fine as well. However, when animating the uvw map modifier (gizmo position) (which has the same effect of a white strip wandering over the object) the density by material function seems to have no effect as no particles are emitted on the white area. What is strange about it... if I manually move the gizmo around in the viewport the particles are emitted always where the white strip on the object but not when I animate the gizmo and hit play. Should these two things not be essentially the same ? It seems that the stack is evaluated differently or the the PFlow does not notice that the mapping gizmo is animated. Please, I would be really happy if somebody could explain this wierd behaviour ! Markus

Topic  977  PF force operator problem
I have not been able to get the PF "force" operator to recognize a "pathfollow" spacewarp as a force. It IS listed as a "force" in the create panel. This is what I'm trying to do: A simulation of particles, SUSPENDED in a medium body liquid, flowing thru a tube that has turns in it. Along the way there are partial obstructions in the tube, changes in tube diameter and other restrictions to the "flow" of the "liquid" that the particles have to react with (ie deflect). What I've tried: Using a spline path down the center of the tube I was able to use a path constraint controller with a "speed by Icon operator" to get the particles to go down the tube and by adjusting the size and angle of the emitter was able to distribute the particles to "fill" the tube side to side. The problem with this is that this approach is all or nothing and the particles, you can't adjust a degree of influence and the particles don't honor any of the collision test operators for the UDeflectors that are the "sides" of the tube and the other "restrictors" (ie deflectors) in the tube. I next tried a gravity force in the general direction of the desired "flow" but the particles bunch at the "turns" in the tube and there was no sense that they were "suspended" in a moving liquid but more like a bunch of bb's pored down a tube rattling around until they found their way to the end of the tube. I when thought if I could use the "pathfollow" space warp as a force operator to give the particle the general tendency to want to move down the tube in the direction of the path, that I could dial it's influence down to a point where that coupled with the deflector collision test would give me what I needed.... But alas, even though the pathflow spacewarp is created as a "force", it apparently is not recognized as such by PF. I could not select it as a force with the PF force operator I guess what I need is a gravity spacewarp that uses a path for it's direction of force ??? Any ideas Thanks Joel Hughen

Topic  975  PFlow after merging in is slow; not caching
This is something I've had a problem with for a while. I'm not sure what causes it, but when I freshly create a particle flow system in a scene, dragging in each node from the dock, everything works fine and dandy. If I put a cache operator in the global node, it will correctly cache the system. However, if I merge the particle flow in, or if I use a Preset Flow from box#1 (which is effectively a merge) the exact same system will be extremely slow, and won't cache itself, forcing the system to re-calculate the system at each timeslider change. Am I missing something here? Is there a reason my systems act slowly after merging? Anyone else experience this problem? The workaround I've been doing ever since I've had this problem has been to completely reconstruct the flow using new _fresh_ nodes from the dock, and copy/paste the parameters over from the old, infected nodes. The moment I copy/paste a node from the old (infected) flow, the new flow will not cache and will exhibit all of the problems of the old flow. So every node needs to be freshly created in the file. Have a good day :) Hope someone knows what's up

Topic  940  speed by icon and particles shift at vertex of path
Im using Max 8 and I have a very simple setup with pflow but not sure why I am getting this problem. I have a spline path that I bound the SSF icon and a series of test cube particles that follow the path. however when the particles near a vertex (this is an S path) they shift and reorient their position as they pass through the vertex. I thought for sure change the verts to smooth (they were bezier) would fix it but same thing. The setup is fine except for this one point. This happen to anyone, and if so how do i fix it?? thanks

Hi Is this possible with the standard max pflow? Or with any of the Toolboxes?

Simple black/white would probably also be ok. Thanks Mark

Topic  929  Debris penetrating through surface
I think this is the best place to post this query.As i just entered this forum although i am not new to particle flow. Actually i just developed a explosion test which have some problem with pf flow. The problem is when the explosion happens and the debris falls down onto surface some of them collide with the surface but few of them get penetrated through it. I am really confused like why its happening, i showed the animation to some people but they also can't figure out what's the problem is, i am posting the screen capture of the pf events of the explosion. Hope to get my problem solved. [url=http://upload5.postimage.org/89974/photo_hosting.html][img]http://upload5.postimage.org/89974/node_particles.jpg[/img][/url] Thanks

Topic  902  accurate blur of butterlfy particles
I am using pflow for a group of butterfles in a swarm. i want the wings to be blurred as they fly. image motion blur just blurs the each butterfly as it moves through space but doesnt take the wings into account. the blur is equal for the whole object (its an animated shape instance). Object motion blur (as i read on here) doesnt work well with plow. it just makes like a 2 frame blur no matter what the settings are. I tried multi-camera pass and got the same strange blur as with object, no matter how many passes or subs i put in. Is there any way to get the more realistic blur I want for this kind of object with out using Vray? Thanks

Topic  890  Pflow collision problem- please help!
Hey all, I'm a PFlow newbie in a bind, so I hope someone can help out! By the way, Oleg, PFlow is awesome! If you answer this post, I'm a friend of Fred Ruff who helped design the interface, I'm sure you remember him (last time I saw him he told me to say hi if I ever posted- I know he would help, but I temporarily misplaced his e-mail address). Anyway... I've got a scene where I'm using instanced geometry (feathers) as my particles. They need to be attached to a surface shape at their spawning. Then some birds (geometry) fly through them and blow the particles apart like feathers blowing up in a pillow fight (basically). Here are my problems... 1) I've got a udeflect set up with the "birds" attached to it and a collision event using the udeflect. I've got upwards of about 10,000 particles and when I animate the position of the "birds" to collide with the particles, nothing happens. The "birds" are editable polys. 2) The "feathers" need to be attached to the surface of another geometry and they don't all stick, some are offset in space away from the object. I can't afford PF Tools to use Lock/Bond so is there another way to make sure they are all stuck to the geometry? This is really important for the shot! 3) I've got 2 wind forces, a drag and a gravity force being the result of the collision event (I'm testing it with a sdeflector). It seems though that the "explosion" of particles starts slow and speeds up (is it inheriting the speed of the deflector?) and I need the reverse. The "feather" particles need to "poof" quickly up & out and then slow down and float to the ground. What are some good settings for the forces and should I use an age event to apply the gravity force? 4) How can I get the 4 or 5 "birds" to disrupt all the particles. Some aren't in direct contact with the "birds", so they don't move. Sorry, I know it's alot, but I'm on a stupid deadline of about 4-5 days, and I'm a bit behind (can you tell? ;) ) Thanks in advance! P.S. If need be, I'll post my .max scene later today.

Topic  888  Any way to use find target but "looser"?
Hi Folks, I use find target a lot as a way to guide particles along but I've found that when I use smaller scale scenes and lower speeds in the find target controls, the particles move in a really linear way between the various targets that I have set up. What I'd love to be able to do is have the particles find the targets overall but with a less linear movement - say for example if I have particles flying along that then get sent into a find target event via a collision or age test, I'd like them to gradually turn towards the target as opposed to immediately changing direction - is this possible? I would use speed by icon along a path but in the case of my current job, the targets are parts of a human body and have to be tracked to live action footage so a spline wouldnt do it. Any thoughts? Cheers for a wonderful tool! John

Topic  882  Animating Shape Instance Scale
Hi everybody! I just came across something quite odd. Forgive me if you already know all this, but I didn't, and this may help others...... When using a Shape Instance, you lose the ability to animate the scale control in the operator. This is different from the standard Shape, where you [i]can[/i] do this. The solution is to place a Scale operator after the Shape Instance in the flow, set it to absolute scale, and then auto key as normal. My first effort to get round the problem involved animating the actual object I'm using as the instance. I scaled it over 50 frames, then turned on Animated Shape in the Shape Instance. Do NOT do this!! This method causes PFlow to work much harder (I'm sure Oleg can say why) and, when trying to cache, I ran out of memory and my scene crashed - recovery failed!!! :evil: As I said - sorry if this is obvious, but I searched for the answer and couldn't find it - so here it is! :D Z.

With this scene i have another problem. I'd like to create "animation veins", that will be spread some kind of fire/energy around. For this i use very awsome script from this forum "PF Spliner 3" ( http://www.orbaz.com/forum/viewtopic.php?t=311&postdays=0&postorder=asc&highlight=particles+path&start=30 )- It was answers for my pray, god bless creators ;) - it's seems working fine, however when i start emmiting particles from created and animated splines, than particles are going only from the top of the spline. and I'd like them to emitt them from whole "drawing" spline not only from one point. Could anyone help me please. Thank you for this awsome forum, it save my life :) Chris

Hy community! The company i work at the moment just swiched to VRay 1.5. So far so good... After a few days of getting familiar with the new features i figured out a serious issue (or maybe did something wrong?): When i use either a static or dynamic material to shade the particles everything looks good in the viewport and renders just as expected and i´m used to with scnaliner. Same goes for older VRay versions (only tested 1.47.x). But VRay 1.5 seems to have issues recognizing wich materialID every particle has and along that wich material has to be assigned. I already tried to wrap a MESHER compound object around the particle system then i converted it to an edit poly and from then into a vray proxy mesh object. finally i assigned the multi/sub material and thanks god the vray proxy dealed right with the materialIDs... that´s, let my cut that short a shitty workaround that works but spends some major time!!! i attached an image explaining the issue a little more visual: [img]http://core2core.de/spielwiese/pflow-vray-material-issue.jpg[/img] Hopefully anyoe can help out :( regards and thanks in advance anselm

Basically, I have a scene of a city block and I have broken this city scene into thousands of mesh elements. What I want to do is create a particle flow event where a particle gets spawned and each individual particle is then attached to the center of each on of these city mesh elements (each mesh element is then linked to the particle). I then want to do some nifty things in PFlow to blow around the city scene to dissamble it in a very creative way. Does this make sense and is it possible. Thanks Paul

Topic  753  Colliding particles, like FindTarget
Hi all, it's me again :) I am now working on a space battle scene, with a lot of PFlow stuff - the weapons, small fighters, effects, all PF. There is a situation, in which a swarm of fighters is flying near a big starship, which fires a storm of lasers at them. I can't figure out a way to guide the laser particles to the fighter particles. The best I came up with is an area effect - using Speed By Icon for the fighters, and linking a Find Target icon to the speed icon. This makes the lasers shoot at the same area, and some random fighters are passed to an explode event. So this is an area effect, and not giving real collisions between particles. And maybe I could get away with it, but I am sure that there is a better way of doing it. Maybe a script, or something in the famed box #3 :) Thanks ;) P.S.: This is my first fully rendered PFlow animation: [url]http://cravenous.com/fworks.avi[/url] - fireworks, of course :) It turned out rather good, and I am having great time with PFlow! Thanks, Mr. Bayborodin!

Topic  614  Particles and displacement
Is there a way to use displacement, say a world space noise and have all the particles respect the displacement. For instance. If I want to have grass blowing in the wind and I want to deform the instanced geo I coutl use a mix map with a gragient to contropl the amount of displacement along the blade and then have a nouse in world space that rolls across the landscape. As far as I can tell rendertime dispalcement is not possible with PFlow. And The displace mod will work just fine except that when you instance the base mesh for the particle it uses the instance for the corodinates not for each particle. This means that all the particles are uniform in their motion. Any thoughts? Cant get mesher to work with it either. Thanks -Michael

hello ! i want to create the following system inside a specific volume: i have a box and an emitter inside. my goal is to let the particles flow on the "ground" (speed by surface) and as soon as they collide with a wall let them be driven (wind1) to the ceiling where they then (as soon as collided) drive along the surface again ... ... as soon they collide with a "wall" (side of box) they should then be driven (wind2) back to the floor again where they continue flowing along the surface ! this should be endless loopable and absolutely interactive (no matter where emitters placed, orientation, number of emitters) best would be if even the collidiing particles from 2+ emitters behave as soon as collided ! thank you very much for your help and sry - i know i am "indeed" new to max (r6) indeed

Topic  558  interaction problem
There is a small problem in my scene and I wonder if I'm alone with this: I have a scene file with 4 PF sources. 2 are currently deactivated but they should get activated once I get to the final rendering. The last 2 were merged from a different scene. After adjusting some animation curves I tried to add some additional operators. But it seems I must have locked one of the particle systems: I can't move several events in the Particle View nor can I move/copy the operators within these events. How did I accidentally lock an event? Or this there something wrong? Sorry for sounding noob, but I feel rather stuck here. T.I.A. ky

Topic  523  Creating a crowd
Hi, I was using a combination of scatter and pointcache2 to render large crowds of people who are seated in a stadium. Making sure I turn off distubution object and a few tweaks I could avoid crashes and render 40,000 people easy, all with offset animation. to get the randomness of position I made a tri for each seat then used a script to randomise selected faces and detach them for each variation of character - slightly tedious I thought I would have a go at using pflow for the same task as it is quick to use groups of characters. easyer to set up. I got about 5000 characters - about 360 to 600 poly each (can't remember exact). Although the memory use seems to float between 500 and 900megs , I left it going and it crashed at frame 40. (I have 2gig mem , running win2k - max8) To make the particles face the right way I use direction to target the icon in reverse so they all point inwards I have them emmit on frame 0 to 0 I keep them stuck in place using position on object I think, so they don't move, just face the icon - direction by speed. Is there any way I could optomise this to use less memory and have less chance of crashing? Is it going to be possible to render 40k crowds without buying box1 ? As the particles need to totally stop and not update other than playing the offset animations, is there any way I can improve the update time?! thanks for any advice, I may go back to using scatter, because although its a pain to set up, it does not crash mid way through renders...

Topic  501  Particle collision with rigged object
Hi guys! I`m new here so hello to You all :) I`ve got this problem which is quite strange for me and I have no bloody idea how to solve it. Well I have rigged object (object attached to the bones using skin modifier) and I have cloud of particles which is not moving at all. Object is also connected with UDeflector and using collision test with the flow. The problem is that when I`m moving bones (so that the object ought to interact with the particles) nothing is happening. But when I move the object (not touching the bones) or if the particles have fairly high speed the collision takes place. I`ve used Xform for the object and still nothing. It doesn`t matters if it`s complex mesh or simple cylinder. It is also important to have the whole system the way I`ve presented (particles which are not moving at all and object animated by bones). I know that not only I have this kind of problem so the answer would be appriciated not only by me. best regards Leru

Topic  485  local space emission
simple sphere is emitting low number of particles with spawn by travel test and drag force. the result is something like ''spikes'' growning at the surface of sphere. after animation of rotation or position of sphere, the spikes are moving out from their original position into the local cordinate system of sphere object. the idia is to lock the movening of particles in local space of sphere. It means that all secondary position and rotation animation of sphere object must NOT affect the movening of spikes and there must be locked in local space of sphere and sphere's normals ;) the idealized variant of this try must work at any type of surface , for examle surface like character skin. i understand that at each moment of time particles must check the position of sphere and correct self position . something like cycled flow . but i cant solve :)

Topic  462  Slowdown during explosive spawning
First, a little bit about the terminology - explosive spawning here does not mean spawning for explosions. It's more about the spawning that has exponential amount curve - say, each particle spawns three new particles per frame. As a result, they multiply rather quickly: 1 frame: 1 particle 2 frame: 1 + 3 = 4 particles 3 frame: 4 + 4*3 = 16 particles 4 frame: 16 + 16*3 = 64 particles 5 frame: 64 + 64*3 = 256 particles 6 frame: 256 + 256*3 = 1,024 particles 7 frame: 1,024 + 1,024*3 = 4,096 particles 8 frame: 4,096 + 4,096*3 = 16,384 particles 9 frame: 16,384 + 16,384*3 = 65,536 particles 10 frame: 65,536 + 65,536*3 = 262,144 particles 11 frame: 262,144 + 262,144*3 = 1,048,576 particles So, in just 10 frames the number of particles exceeds the default particle amount limit (100,000), and in 11 frames it exceeds 1 million. It would not be so bad but... If there is a Shape operator then the spawning process forces the system to copy the mesh information in-between particles. And mesh data is HEAVY. Therefore significant slowdown may occur. The only work-around that I have found is to use Box#3 in a specific manner. Namely, use Cache Disk operator to record the spawning with the Shape operator disabled. The Cache Disk operator allows to use PFlow operators on post-cache basis, so the Cache operator can be plugged in as a post-cache operator. This is much faster because in this case the mesh data is shared between particles, and no copyind of mesh data occurs. Thanks, Oleg B.

Topic  457  birth scripting
Someone please help! i am having problems when using vray (1.47) motion blur.

Which it normally does in most situations when particles are still being born. I know vray 1.5 has true motion blur for particles, but i dont have it! SO............ I am tring to write a script that will offset the particle creation but have them hidden (or transparent, or infinitly small) but they act in the same way during the rest of the events. basically so they are all created at the same time, but can then be controlled by normal operators. and it all has to be done in a single event!!! any help out there? many thanks

Topic  446  exploding character
Hi All, I was wondering if anyone could shed some light on this example that I would like to create using PFlow. Basically I have a character that needs to break apart into pieces and possible come back together. The mesh itself is already modeled into pieces, meaning it is a series of indivuadal pieces of geomotry. I would like to use the actually geomotry as its particles or at least make it look that way. The character will be doing some sort of action, running, jumping etc then striking a ball. When the character strikes the ball he will break apart. Think of a chain reaction, starting when the character kicks a ball...from the shoe to shin, to thigh all the way up. While I am a experience in 3d ( maya and max ) I have not done that much production work with pflow in 3ds max, I know the basics of it. I should mention that the animation is being done character studio using mocap data in 3ds max 7. Any ideas of a starting point would be great. Also any reference sites and your tutorials that deal with issues like this would also be greatly appriciated. BTW I have ordered a few of Allan dvds from cg-academ to learn from but they have not arrived yet. Thank you for your help. Regards Alex

What I've got is a pflow emitting with a volume but i need to hollow out the center of the volume, make a spherical void right in the center. Most of the stuff i've done to achieve this really slow down the system: for instance, i tried having them emit from the surface of a sphere and then stopping after a time...but between the speed and the age test and the second speed it was taking 5-10 times longer to calculate...which slows everything down...and slow is bad ;) any help would be really appreciated...thanks so much -brandon

Topic  395  Particles leave pipe although pipe is Deflector
Hi I have a particle flow system where i want to send particles through a pipe and they shall fill always the whole pipe. The pipe looks like this: ----- \ --------- and has different bores. I thought now of the pipe as a Deflector, but sometimes the particles fly back and this will destroy the illusion of a stream. Thus i tried to apply several Find Targets within the pipe to give a specific way for the particles, but they don´t get always near enough to the targets and thus don´t find their way to the next target. Second problem is also, if i apply also a collission with the pipe as deflector to keep the particles within the pipe, the collission doesn´t get respected. event1: find target --> event2 if close enough collission (the pipe) display1 event2: collission (the pipe) display2 collission is both set to bounce. Already thanks for all ideas/infos Azrael

Topic  392  Postion Obj, density by material problem with cylinders
A simple problem so i'm sure that this is either a known bug or i'm just stupid! I want to emit particles using the density by material option from a cylinder. This works fine with 2d maps such as chequer or a regular bitmap the problem is when i want to use a 3d procedural such as noise or cellular. The particles do not emit from the correct place. It works fine with planes, boxes and spheres but not with cylinders or teapots. I have set the mapping coordinates to explicit map channel which i think should be correct but it doesn't work properly. I know i could bake out the procedural map as a texture but i need to maintain a procedural workflow as I will be animating maps and using them to drive other things such as shading and displacement. Any help most appreciated.

Topic  330  deflector probs
Hello all, my first post here, so thankyou in advance for providing both creating p flow, and providing us with a method to discuss. I am having problems with the u deflector and pflow, I have a simple cylinder (about 16 polys) which is linked to the u deflector, and a p flow with about 5000 polys. now the calc takes about 20 mins to ramp up. Turn of the collision no ramp up time. if i build the same cylinder shape out of regular deflectors (14 of them) ramp up takes about 5 mins. This is an ok work around but seems a little silly. is there a simpler way to do simple object deflections. Or maybe a set of simple shape deflectors (like the s deflector) oh yes and when will we be able to purchase tool box 3? I need it yesterday, heh. thx sam

Topic  322  Orbiting particles
I'm trying to set up a Flow where particles generated on a plane will orbit on a stable path around an object . The closer to the object the faster the particle will orbit. At a specific time the orbits will start to decay and the particles will orbit in ever tighter circles, speeding up as they get closer to the center. To make things even more complicated I'd like to have each particle have more particles that would orbit around it. The final effect would be something like a solar system of planets and their moons collapsing into the sun. If it was only a few objects then linking and animating them by hand would be a simple solution but I'd like to use p-flow to control thousands at a time. We will also be creating multiple animations with varying gravity/speed settings so a procedural system seems the best way to go. I've made some progress on the decaying orbit using a force operator and a vortex space warp but I can't use the same method to create the stable orbits of the first part. I've tried position object to lock the particles onto an animating mesh until transferring them to the decay event but that is not very flexible and the change is very abrupt. Is there a better way to have particles orbit a specific point?

The problem is, that I can't figure out how to emit those (boxes) from the surface of first particles (cylinders) not only from their pivot point. Better example would be ice crystal forming or tree growing. Do I need to mesh the first particles someway before PFlow understands them as geometry ? If so... any pointers on how to proceed.

This is a problem i've had constantly throughout my use of PFlow and i've never really been able to resolve it. Once my PFlow scenes get complex, things start going funky with the render of a scene not correlating to the viewport view of the scene. With my current scene, I have not yet successfully rendered what I actually see in my viewport at all lately. I'm not sure how to fix this, but throwing in Cache's on certain areas and removing them etc. hasn't helped... How can you fix this? It's quite difficult previewing your flows when what you see in the Viewport isn't what comes up in the render...

I was trying to help out a fellow artist who found what might be a bug. He has multiple objects emitting particles in the fasion of fountains. The issue is that when Variation of speed is used in conjuction with Divergence, the fountain heights do not all reach the same level. The greater the amount of either of them , the greater the unevenness. I would have chalked this up to 'just the way it is supposed to work' except that there seems to be a pattern in the unevenness, perhaps related to the order of the objects within max (thier order of creation?)..the first being the shortest, and the last being the tallest. Can onyone shed some light on this? If need be, I can uplaod a scene demonstrating this.

Topic  290  Flow Joining
I have a setup of a curved tube that particles follow using an animated icon and a Speed By Icon with offset by particle age. I have another flow coming from 3D space that needs to join this flow (all along different points of the flow) and follow the tube. Think of sprinkling dust in a river, except on every axis. I've tried a find Target--> Mesh and then set the speed by surface parallel, but the particles need the z axis of the face, if that makes sense. Directional. I've also tried a Keep Apart with negative value trying to keep them close to the flow, but they don't inherit the speed of flow 1. Any suggestions? Just wondering if anyone had anything before i started scripting something. Khye

Hi everybody i tryed everything but i can't get the geometry to hold the particles and not losing them i placed two examples online in *.mov format i also placed the original files online the "blizard szene" is done with the blizard emitter the "pf szene" is done with particle flow (without any keep apart groups) these are two peaces from the end of an 890 frame animation where you can see how particles break throug the wall of the closed tank and even seem to be shoot away in the air (look at bottom of tank) can somebody please tell me what to doo??? because otherwise i would have to retouch like hundred of pictures :( [url]http://www.neuhaus.com/3dmax[/url]

Topic  275  How do I cache everything except the shape operator?
When caching a particle system the memory hog is usually the animated shape operator. How can I cache everything except for the shape operator. The only solution I found was to spawn every particle on every frame, apply the shape, and then delete all with lifespan of 1. This doubles the number of particles. Any advice? Thanks, Ben.

Topic  274  Long runup?
I have a scene with 3200 frames. The particles are age tested to 220 frames and are then passed to a delete. But when I go to the end of the sequence, it takes MUCH longer to do the update then at the beginning of the sequence. There are no Keep Aparts or Spawns or anything that should make for a particle-particle dependancy, so why does it take so long to evaluate? Does Pflow not care that all the particles it is evaluating die anyway long before trhe current frame? As my scene is so long, I can't really cache the particles either. I'm getting killed on the renderfarm. Any ideas on how to make the scene evaluate quicker? - Chad

Topic  273  Force Operator Influence
hi, I was wondering how the influence is affecting the particles... when I try to animate the parameter to something like this: 0%---10,000%---0% 0f--------5f--------9f at frame 9 onwards, the particles are still moving even though the influence is already set to 0%. Same thing happens if I animate the force (wind) spacewarp instead of the influence. I was leaning towards being able to control particle motion using the influence parameter, I was only able to achieve the effect by animating it like this. (0%)---(10,000%)---(-10,000%)---(0%) 0f-----------3f--------------6f----------9f (same thing also happens if i animate the spacewarp itself) I suppose it needs to be balanced, which makes it kinda hard to control on different occasions. I usually place another force operator with a drag in it to controll the way it stops, it works wonderfully. :)

Topic  263  rendering interupted PFlow sequences cause problems
I just encountered a strange thing in PFlow. I have actually encountered this a few times in the past, but was unaware until now what was going on. I have a flow of a bunch of particles locked to an animated surface (it is like the Rock character I posted in the User Gallery). I have particles in place and locked to the hands. At certian points in the animation the hands collide with a deflector and the "hand" particles are sent out to a Stop event and piped back into the Lock/Bond event. It works very well. However if at any time I stop a rendering after the intial collision and restart at the nex t consecutive frame, the hands are not always in the same location in the proceeding frames and I get a jump in the final rendering. Also, I set a sequence of frame (ie 451, 505-600...) where frame 451 was mid collision for the hands and 505-600 was after the hands were pulled back away from the deflector. Upon rendering this, frame 451 was correct, but 505-600 rendered with the hand particles detached and still in place from the collision. Basically what I am seeing happening is that on many occasions the particles work fine when rendered in sequence, but in certain flows they do not work if rendered out of sequence. I would assume that this is why some have had problems with network rendering (there was a post on CGTalk). Idealy, the Cache operator should handle this if set to use at render time, however it doesn't always seem to. So, finally (whew...) is this an error with my flow logic or is there perhaps another way to avoid this that I am not seeing? I have had similar problems with slightly complex flows involving Spawning.

Topic  259  Particles disappearing when using Split
Here is my flow: [img]http://helvede.net/temp/pflow_view.jpg[/img] When I preview or render the sequence, atleast a dozen of the particles disappear a little over time.

Topic  248  Donut vortex daemon
Hi all!!! :D I´m trying to make a donut vortex daemon (like the lightwave one) but not sure how to acomplish the task at all. I´m thinking of using a torus object and make particles that goes trough the main hole, go back traveling along a path dependant to the distance to the iner radious of the torus. I mean, the closer the particle is to the inner radius, the shorter is the path it´s going to take. You know what i mean?. :? What do you think guys? What would you do? Can I use the lock/Bond PFlow event in order to help me? Cheers.

Topic  242  Animated spin
I'm trying to get an object to spin really fast and then slow down over time. I thought I'd be clever and use PFlow with a shape instance, and a spin operator to control the spin speed. But it seems that you can't animate the spin rate. I have keys on it going from 3600 to zero over about three seconds, but the shape never slows down. It the spin operator not meant to animate, or am I doing something wrong? I know about the Stop Gradually operator, and it does a pretty good job, but it would be nice to have more control over the spin rate, like modifying the animation curve and being able to have it slow down, reverse, and then gradually stop.

Topic  239  UDynaFlect allows geometry to stick through
I'm new to this forum and expect there are some pretty hardcore particle gurus here. Hopefully you can help me solve my issue/lack of expertise. I'm building a clear plastic jar in Max 7.1 for a client that is filled with hundreds of tiny plastic tubes. I've tried Particle Source, Rigid Body/Reactor and Particle Systems with Deflectors to try to simulate the actual product. I'm having two problems: 1. I can't find a method that allows the instanced geometry to pack tightly together, nesting as if poured into the jar to fill all empty spaces. I've tried Keep Apart in Particle Source, I've tired pouring thousands of instances in using Reactor and I've tried a Particle Cloud. 2. All methods allow geometry to break through the deflectors. I've increased the mesh of the container thinking that might help but it seems to have no effect. I can't seem to find any setting that will strengthen the force of the deflectors, specifically (the one I'm currently trying) the UDynaFlect. I'm attaching an image that shows the actual bottle on the left and my current status on the right. [img]http://nvisionanimation.com/guest/ParticleBreakout_01.jpg[/img] The 3D image has a cylindrical mesh with a UDynaFlect attached. A PCloud is used to fill the space. You can see the geometry poking through (which is occurring with every different type of deflector I try) and you can see that there are air gaps or spaces. The geometry instances are packing tightly and using up all available space. I'm also trying 'Use Subtree' which is helping to reduce the clumping but I still get the leaks. Here is a view of that. [img]http://nvisionanimation.com/guest/ParticleBreakout_02.jpg[/img] Any suggestions would be welcomed. I'm doing this for a job and need to resolve it soon. Regards, Rob Holmes

Topic  235  particle chain?
Hi everyone, does anyone know how the following effect could be achieved in particle flow? I am using pflow to simulate a growing flower: the blossom is attached to the pflow emitter, wich is animated along a path. sphere particles emit from the pivot with zero speed, forming a tube with the blossom on top of it. occasionally, additional leaf-like particles are dropped, also with zero speed. so far it works fine, the flower looks nice. now i want the flower to sway gently in the wind. I would like to glue the particles together in the shape they are aligned right now, so I have a more or less stiff chain, that can bend under the influence of e.g. a wind space warp, but not break apart. is anything like this possible in pflow? (I am not exactly a maxscript wizard. I don't know a single spell) thank you for meditating on my problem.

Topic  229  Go To rotation on a single axis only?
I would like to stop my spinning particles nicely (= ease out). So far, I tried using Go To Rotation, but unfortunately, this operator seems to rotate around arbitrary axis directly towards the target orientation. What I am looking for is a way to restrict that Go To Rotation movement to one axis only. So it will rotate the particle around the x-axis only until it is as close to the target destination as possible. Any ideas/thoughts on how to do this? Thanks! -- MartinB

Topic  222  Random emission points
I'm wondering if it is possible to setup a system that randomly emits particles from a group of chosen position objects. For exmaple I have 4 seperate faces that I have included in an position object operator and I have setup a noise controller to drive the birth rate. As it stands right now each face is emitting particles at the exact same time based on the rate and I'm trying to find a way to birth them raodomly from the 4 faces. I know I could accomplish this simply by setting 4 different events and using a different seed on my noise controller but maybe there's a way to do it using a script or something. thanks!

Topic  216  Progress on renders of nebulae!
To whom it may concern-and perhaps to new users who likewise show up here quite lost... Rendering the nebulae...1)"PF source" w/render seems the most relevant pane...adding the "shape plus"(unique to the Orbaz plug)-finally got me a rendering result...experimented with hearts and texts...noticed they were all coming out with shading exactly the same as the "display dots" parameter in the same pane...since that "display dots" color info seemed to be overriding all of my attempts to add a gradient shader...finally created a camera from the default "perspective" view...in "Particle View" deleted the "display dots" from the "PF Source pane" and replaced it with "Shape Facing 01",which allowed me to program a Blinn to a gradient and start getting some satisfying renders of this nebulae in motion... What took about seven hrs to decipher I am fairly positive could have been explained clearly in two minutes by anyone posting on this site...better to promo friend's training vids I guess-that send me on endless perusals of the abstruse programming-that in no way leads me to the simple rendering question I asked in the first place..would have been nice to have been appreciated and supported as a new customer seeking to learn a bit :roll: .

Topic  210  emit particles from a spline
Oleg- No doubt you’ve been asked this a dozen times but here I go anyway. Is there a way to emit particles from an arbitrary spline without converting it to a mesh? And from a purely technical curiosity standpoint, if it isn’t possible currently, is there a problem with doing so on the dev side? As always have a lot of fun with the tools. We are currently working on another feature with lots of Pflow. Sin City which comes out Fri had a ton of stuff as well. Lots of snow! And some blood.

Topic  208  PFlow (standard) mapping problem
This may already have been covered by a "Get Toolbox 1 answer" but I'd like to give it a shot anyway. :roll: [img]http://helvede.net/temp/browneyefly.jpg[/img] In the example below, I'm using this image as the diffuse mapping in channel 2 and a bitmap mask in mapping channel 1. Channel 2 uses a Mapping operator in PFlow while channel 1 uses the UVW map from the instanced geometry used in the system. All seems to work fine, until the system reaches the Split operator. Then the mapping seems to slide.. Do I have to purchase the Toolbox, or can this be worked around somehow? This is a downsized version of larger scale scene with a similar effect. In the other scene I used a modified bobo Birth script to instance the geometry from existing objects (30.000+) which was pretty heavy.. So I'd very much appreciate it if that could be avoided.

Topic  199  Particle Dynamics
I'm doing some tests where my particle system is using instanced geometry, and these pieces are falling onto a box object. Now because the particle is still being treated as a simple vertice with a piece of instanced geometry around it, when it hits the plane the instanced geometry goes through the box object until the vertice comes into contact with the box's surface. Is there anyway to treat a particle as a true piece of geometry so that when it collides with another object it is using the instanced geometry as a collision point and not the vertice? thanks!

Setup: Speed by icon operator, icon with path constaint. Stop gradually operator. Problem: particles stop correctly but there is no gradual about it. When I have a normal speed operator it works fine. Putting a speed operator right after the speed by icon doesn't fix it. PS: Drag Force doesn't have the desired effect, either. --edit: as a workaround for now I've animated the speed variation min an d max values from 100% - 0% in the speed by icon for the duration to slowdown the particles along the path.

Topic  188  Help with army moving over terrain
I'm using PFlow to set up an army marching over hilly terrain. It's working pretty good so far, but there are a couple of issues with it that I would like help on, if possible. Here's the basic setup: Particles using a mesh object for position, Speed by Surface using the parallel option to keep them following the ground, a wind modifier with negative force to get them moving forward, rotation using speed space, and shape instance for the soldiers with offset animation. Issue 1: Eventually, some particles (or soldiers) will start going into the ground or rising above it instead of staying on the surface. I'm guessing that using Lock/Bond would help with that, but I don't have the PFlow Tools. It's possible I can talk the company into purchasing it, but for right now is there another way to handle this? Issue 2: There are some creatures in the army that behave more like bugs than people, so I want them to follow the face normals as they move over the terrain, instead of staying upright the whole time. So basically I would like to be able to use Speed by Surface using both the parallel and normals options at the same time. Is there any way to do this? Here's a link to the Max 7 file, minus the actual soldier geometry for contractual reasons. But you still see what's going on with the tetra shapes it's using instead.

Topic  152  Detecting angle of impact on collision
Hi guys I'm new to the forum I'm trying to figure out a way to control parameters within the collision spawn test by the angle at which the parent particle hit the surface the effect i need this for is blobs of paint hitting a wall and floor... when they hit the wall full-frontal they're supposed to explode in all directions, but when they hit the ground at a smaller angle the paint is supposed to splatter mostly in the direction of the parent particle. all i really need is the divergence parameter of the collision spawn to be controlled by the angle of impact :) can anyone think of something?

Topic  150  Cache operator using lots of memory at render time?
Hi, I am currently trying to render a large number of particles that have objects placed in their shape channel. The process is pretty memory intensive and I can only render about 6000 particles before max runs into memory issues. Because of the slow ramping load up times, I am trying to use the cache operator, process all of the information and save the cache with the max file. However, if I try to use the cache operator and render my scene with that many particles, I get a std::bad_alloc error and max crashes out. Any idea why this is happening? Nelson

Topic  149  Video Cards, Ram, and PF Performance
Just a general comment... When I upgraded from 1G to 2G, I noticed a pretty good improvement in PF perfformance, and I just swapped out a GeForce Ti 64M with a NVidia Quadro 4 900 GXL (which is a fairly old card)...and now I am able to fragment birth scripts with 10,000 faces. Ironic, but the Max Core has a real issue with even having 10,000 mesh objects in its database, whilst Particle Flow does not...it took two hours to break up a 125 segment sphere into 7,750 separate objects, and only minutes in Particle Flow to design with them!!! So, yes, Ram matters, and yes, video card absolutley matters...

Topic  145  O.k. Particles every where. Now what?
I don't know if it's my thinking but I don't get how to utilize the particles. I'm aware of using a facing 2d plane with a map utilizing opacity but this seems limiting (very limiting.) What I never see discussed is what to do when you have the particles doing what you want. For me it's a gaping hole in the process as I never see it discussed. Is it so easy that nobody bothers to mention it? What are some of the ways to utilize the particles so that you have visible objects in the viewport. I often imagine particles equaling dust. And that I can assign stuff to the dust but I can never figure out how to do it for: Sand, rain, dust, birds, that floating bag from 'American Beauty' lol, a illuminated spiral of plasma or whatever else have you. I do know about having a group of splines that act as seperate objects during an explosion or such but that's of little help in any thing but explosions. So what are the different ways of making use of the particles?

Topic  27  PFlow Color
I read a [url=http://www.cgtalk.com/showthread.php?t=182858]question[/url] at the CGTalk board and thought about a way to implement it. The question is about the ability to assign random colors to new particles. The most efficient way would be to use the Mapping operator. Unfortunately, as of the moment Mapping operator has a bug that doesn't allow mapping values to propagate to the next events. Nevertheless, I created the scene and put the Mapping operator where it should be. To overcome the bug, I used a Script operator in the next event. So, basically a Mapping operator assigns different mapping values to new particles. A float noise controller assigns the same value to particles if they enter the event at the same time. Then I used a gradient texture with different colors. The result: particles spawn from the same parent have the same color but each batch has a different color. The example scene to download is [url=http://www.orbaz.com/forumData/scenes/20041031/DifColorsThruMapping.zip]here[/url] (24.7KB) Thanks, Oleg B.

Topic  25  Enable Particle Vector Script Channel (SDK)
Hi Oleg, I am developing a PFlow Operator with the SDK and have hit some walls. First, I remember there was a dedicated PFlow SDK Help file when PFlow was still an extension to 5.1. I cannot find it anymore and feel it would be good to have. Second, I cannot figure out how to enable a MAXScript Vector Channel from my code. Basically, the C++ equivalent of the scripted handler on ChannelsUsed pCont do ( pCont.useVector = true ) If I place a Script Operator with the above code before my operator, I can access and write to the channel using chMXSVector = GetParticleChannelMXSVectorWInterface(pCont); ... chMXSVector->SetValue(particleIndex, position); but I want to ENABLE the channel explicitly in my operator if possible. The reason I am doing this is to write my calculated particle positions into the Vector Channel to be used by a Find Target Operator set to "By Script Vector" Hope you can help (I know you can! :D ) Cheers, Bobo
