Topic  2280  PFTools Box 2 Tutorials Poll
[i]I posted this at the Society as well, and thought I would put it here rather than the Box 2 section because this is pretty much "General Discussion". I understand if it gets moved however. [/i] Oleg has asked me to produce a series of tutorials for Box 2. This is a great opportunity for me, but I want it to be a great opportunity for you guys as well. I know that there are not alot of people using Box 2 (or at least not broadcasting it) so this may not yield the results I hoped for, but I am hoping to gain some feedback into what you guys would like to know about Box 2. I have been kind of aimlessly wandering around the plugin for awhile as I find time between projects, but I am wanting to actually sit down and develop this training. With some new hardware and software advancement on my end I am able to free up my main workstation from having to render. That means I will have much more time for projects like this. Anyow, what would you guys like to see? What would you like to learn about Box 2? [quote]NOTE: This is a poll about ONLY Particle Flow Tools Box 2, Box 3 comes later. So please dont request tutorials or concepts for tthe native PFlow system, Box 1 or 3 just yet. I will likely poll the community for those as well if the time comes.[/quote] These are the things that I am looking for from you guys to really make this training great: 1. Concepts: What practical projects would you like to see and learn how to use Box 2 within? ie. Collapsing buildings, swinging lamps, holes being blown in walls, etc. NOTE: These are not compositing and modelling tutorials except where necessary, so the focus is on the dynamics portion of the examples. 2. Theory: What specific operators or troubleshooting issues would you like to see demoed? ie. Basics of the particle skinner, the theory behind Box 2's integration with the original operators, etc. 3. Troubleshooting: What are some common problems that you and many others have faced in working with Box 2 that you think are worthy of a training video to demostrate either work arounds or avoidances? OKAY, that is all I can think of at the moment. This training is up to you guys, because I am an aspiring TD and consequently lack what most of you guys have in the realm of creativity. So give me your problems so I can solve them. - Evan Schaible www.ParticleFlow.net PS: There is no release date set for the training, but once I get rolling those things will be more foreseeable.

Topic  2249  Cracked version of Box#2 Pro?
Some folks just amaze me - http://forums.cgsociety.org/showthread.php?f=206&t=775395 Nevertheless, since the Orbaz motto is to satisfy the customer any way we can, I created a simple web form to simplify a request for a cracked version of Box#2 - http://www.orbaz.com/request/CrackedBox2/ Enjoy! :) Thanks, Oleg B. P.S. The aforementioned topic on CGTalk forum was removed - since it was about cracked software. Well, we are still going to keep our request form :)

Topic  2235  Box 2 and real world physics
Hi I've just watched the demo movie and have just got my jaw off the floor - truly excellent stuff. I was wondering about using Box 2 with real world forces. Can I set up scenes using real mass and force data etc and expect realistic results? By realistic I mean real world and not Hollywood. This would be good for teaching physics or even engineering simulations etc. Kind Regards Garry Clarke

Topic  2203  lock bond problem again
ive run into the old lockbond problem again -specifically the incorrect behavior one - where any modifications of the operator send particles in random directions and renders it useless. although opening the scene again seems to make the particles behave...it makes it impossible to work/adjust a scene when the operator does this. i fixed it before with a complete/total reinstall and reauthorisation. that hasnt worked this time though. what causes this? im using 1.07 box 1. also, if i want to download the latest version/redownload...where do i do that? as any download seciton only lets be download demos. cheers

Topic  2163  ScriptOP, Mesher + PointCache= no update
Im using script operators to grab the shape and motion of multiple scene objects, using a mesher to turn the pflow in to an object then point cache-ing the mesher to bake out the whole system. Everything works fine until I try to record the Point Cache. Its like the script operators are not updating during the point cacheing. How can I force it to update? I attached an example file, hit record on the point cache and watch it not work!!

Topic  2030  Rotation to Normal?
Afternoon all! I'm having a bit of trouble. I have a scene with a geosphere object, which I'm using for a Find Target. The particles move out from the source in all directions, and a Data Test checks their proximity to the geosphere - if they get close enough, they enter the Find Target event. The problem is that I need control over the "docking" rotation of the particles when they reach the surface of the geosphere. Imagine the particles are all shape instances of a capital T. I want them to land on the surface with the bottom of the T hitting the surface, and the upright part being aligned with the surface normal at that point on the sphere. I have tried with a GoTo Rotation along with a Data operator, but I can't get it to work. I've used 2 Geometry SubOps to get the Closest Point by Normal and then the Point Normal, and tried feeding the vector output of this into a rotation Output, but it doesn't seem to do what I want. I've seen Oleg referring to Surface Alignment in Box 2 - though I can't see that option anywhere in the documentation..... - but ideally I'd like to use Box 3 to accomplish this. I'm sure it's possible.... I'm just missing something.... Oh, and another thing which is annoying me is that I want the find target to use Surface Normals as its direction so the particles move around the geosphere a bit before docking.... but I keep getting particles traveling through the sphere :( Any help with either issue would be immensely appreciated! Z.

Topic  2017  Help with Find Target... please!
Does anybody know of a way to ease in the start of a find target operator? When particles enter a find target, they change direction to move towards the target. Unfortunately, this change is sometimes very abrupt and pronounced, especially if the particles were heading in a different direction at that point. The "Ease In" option in the operator only affects the end of the process, not the start. If you visualise the trajectory of each particle, I guess I'm wanting to "bezier" the point at which the particle enters the find target process - just round it off a bit. Any ideas? I have access to all 3 boxes BTW... Many thanks for any suggestions, Z.

Topic  1924  Stick to surface and spawn by speed
I am trying to get particles to stick to a moving object and if the particle's speed is above value x send it to another event for spawning, then if the particles speed drops below value y it will go back to the first event where its not spawning. Spawn by speed did not give me the results i wanted and sending the particle back to the initial event randomized its position so particles would disappear from areas that move and stop a lot and bunch up in areas that moved very little. Is there a way to have the particles stay where they first positioned on my object? Here is an example scene. I do have box 3 so that is an option.

Topic  1870  Animated Scattering along Normals
It's been a while I haven't been using PFlow, so this might sound a bit naive :oops: ... I just want to keep scattered objects aligned to the surface normals based on Bobo's famous "Hairy Teapot" tutorial. I've been using "Control Speed Continuous" and "Speed Space Follow" to keep the object aligned, but it creates some strangly flickering animation, even with a simple bend and subframe sampling...

Topic  1856  CG-Academy - The PFlow Script show
Is available. Post taken from CGtalk... PFlow Scripting Tutorials Due Soon from CG Academy Just thought I'd give a quick heads-up for a new series of tutorials that CG Academy is due to release very soon (think days, no weeks...). I say tutorial, rather than DVDs, as at first these titles will be available only via download. Rest assured though that after a short period the same articles will be available for purchase on DVD media. Releasing via download allows us to get titles "on the shelves" just as soon as the material is available. With physical media following soon after. What are the titles? We'll we have an Advanced level series called Particle Flow Scripting, and it will contain two titles, The Pflow Script Show and The PFlow Script Show : Act 2. The first of the two titles teaches the basic framework of MAXScript access in Particle Flow. You'll really need this tutorial to get on your way with scripting Birthing, Tests and general Operators. It explains how 3dsmax works under the hood, giving you an insight into its use of channels, particle IDs, Event Indicies and so on. The tutorial culminates in a number of real world practical examples, including all of the script access points. A must have title for any serious Particle Flow TD. [img]http://www.cg-academy.net/boxart/104_BoxArt_INTERNET.jpg[/img] The second title then takes these basic principles and starts to expand the scripting boundaries outside of pure Particle Flow. Here Bobo will show you how to make particles move along splines. How to define targets for your particles, how to move scene objects (including lights and helpers) using particles, and bake that motion into animation keyframes. The tutorial culminates with Bobo showing you how to create a production ready particle animation baking utility, and how to build PFlows in a procedural manner based on the collisions of a Reactor simulation. Once again, pure TD gold. [img]http://www.cg-academy.net/boxart/105_BoxArt_INTERNET.jpg[/img] More news on these as an when they are released. Please spread the word. If you have any questions, please ask away here. Cheers __________________ . Chris Thomas www.cg-academy.net

Topic  1823  simulating grass movement
hey guys, i'm still a newbie in the pfflow. it'll be great if someone can help me with this. i'm trying to make something like this in the gallery. http://www.orbaz.com/gallery/?id=8 like the descriptions said on the above page. "The Lock/Bond operator can control both positional and rotational bonding of particles. In this test the position of particles is firmly locked but rotation is flexible and is influenced by Force operators. The Group operators restrict the area where the wind forces are applied." i get the concept of using the lock/bond to lock the position and using the rotation. my attached scene is pretty simple stuff. but not sure whats really wrong with this. any idea guys? thanks. attached file is max9 version

Topic  1815  Can I make a PFlow Event trigger a modifier?
Hi, I have a stack of papers (shape-instances) that I blow away as soon as a collision object penetrates them. They are all flat on the surface. On the instanced shape I have a Bend modifier that is turned off. I wonder whether there's a way to gradually turn that bend modifier on, per particle, as it gets lifted by the collision trigger. In short - I want my flat still papers to turn to bent papers when they are lifted into the air. Is there a way, perhaps, alternatively, to link a morpher slider with that trigger? Thanks.

Topic  1803  Advise a beginner
I'm a student at Southern Methodist University, in a program focused on creating art for games. In my Directed Focus Study courses, I've been introduced to pFlow in Max, and I've gotten a reasonably good handle on it, torn through a lot of Pete Draper and Allan McKay tutorials, and done some stuff on my own. I've come to the conclusion that I'd like to pursue VFX as a career direction. I've got a small amount of money set aside for educational purposes, about enough for a single piece of academic software and a couple of books or DVD tutorials. What resources would you recommend to someone new who wants to learn to be a better FX artist, and begin to assemble a portfolio?

Topic  1800  integration steps
hi i am spawning particles with no speed, no spin, to produce a trails effect. My emmitter has a path constraint and it is winding around and looping lots pretty fast. THe problem is that no matter how much I lower my integration step, they don't extract the positional data on a dubframe basis so my trails are not smoothly flowing like the spline upon which the emitter is travelling. There is an improvemt when i go to half step, but anything beyond that simply does Nada! the half step is not enough. If i apply a force and get the spawning to be driven through this, the integration steps works as it should, but it seems it doesn't get the translation data in from max properly on object translation? any help please? cheers Paul

Topic  1797  help with scripting particle orientation
Hi, I'm trying to get a bunch of leaves falling off a tree onto the ground. I've used Allan McKay's method of first positioning the leaves on the ground and then have them find that target position based on their stored original position in the vector channel. My problem is - I want the leaves to spin as they fall - and if I do that then they penetrate the floor with various rotations. I've added the use orientation channel in the first event and could print out all the orientations of the particles on the ground the way I want them to be (pretty much all have 0,0,Z - where only Z has an angle). I can probably store all those orientations in an array but: 1 - I don't know how to access that array on the next event (seems like global arrays or variables don't transfer from one script operator to the next - or - just my lack of knowledge?) 2 - Even if I did get the orientation values - how do I use them? Since the particles will enter the next event one at a time - can I constantly run an IF statement on all the particle count and assign the new orientation to all even though not all are there yet? I tried the Goto Rotation node but didn't seem to have any luck with that. Once again - maybe I'm just not familiar enough with it. I don't know if I'm clear enough with where I'm stuck - I'm just interested in having the leaves rotate and then ease into a horizontal position on the ground level (laying flat). Thanks.

Topic  1781  interCollision for instanced objects.. is it possible?
Hi, I'm wondering if this is possible with the box3 or 1 plugins.. Using pflow instancing geomety using the shape instance and have those instances self collide with each other. From what I've read I understand only box3 is able to make proper inter particle collison with pflow, but still, is it possible to make it work with instanced geometry? Thanks!

Topic  1757  bake particles animation to individual objects
I have a pflow which generates a number of simple planes and controls their animation. Is it possible to bake out this animation so that each particle becomes an individual object with baked in keyframes for pos/rot/scale. I know I can use the mesher, but it results in shape animation rather than standard translation. Cheers Paul

Topic  1746  Speed by Icon Divergence from Path
I have a couple of helix splines that are WSM Path Deformed to a single, simple 4 vertex spline. This allows me to do vertex animation on single spline and have the helix splines deform to match the single spline. The single spline is linked to a dummy and the dummy is animated moving across the screen. So basically you've got: moving dummy, and a vert animated moving spline (which deforms 2 helix splines). I have a simple PFlow setup where I use a Speed by Icon with Path Constraint that moves the icons down the helix splines. All this results in an animation showing a moving vortex of particles that move across the screen. Problem is, the particles start out following the helix splines perfectly but later they diverge from the helix splines and the later still, they return to follow the helix splines perfectly. I can't seem to get them to stay on the path the whole time. I have bumped up the accel limit but haven't seen any change. Any idea what I'm doing wrong? Thanks!

Topic  1742  Birth Material Operator AND Birth Script... is it possible?
I would like to use a birth script to define object chunks, but the timing of their creation defined by a birth material operator. Is there any way to achieve this? Ie the position of the seeds specified by the existing location of scene goemetry, but particles only being birthed when the material of the emitter is white.

Topic  1739  particle view problems
How can I get rid of a particle view null that pops into files if u accidently open Pflow. it only is visable during merge, but sometimes seems to cause errors, and at the least makes me have to overwrite if I am using P flow in another scene during merge. eithier way a hassle. cheers sam

Topic  1738  Per frame script to limit particle amount idea.
I have a scene that causes serious memory problems when my particle count goes over 100k. I was thinking a cheap way to avoid rendering the scene in multiple passes would be to write a script that is executed every frame prior to render that :- 1 - Counts the number of particles in the scene 2 - If count > threshold do { 3 - Change render "Quantity multiplier" to reduce rendered particles to below threshold 4 - else render multiplier = 100% This would work fine in my scene, as by the time I need to start culling particles, having random particles disappear from the render 'probably' wont be visible. Is this the best way to limit the number of particles rendered? I know I could reduce the overall number of particles in the scene, but for parts of the animation where the camera is close to the particles I need the higher density of particles to be visible (it is a forrest). No doubt there is a far more straight forward approach to this problem that I'm just not aware of! :)

Topic  1733  Birth Texture and particle Amount
I just wanted to clarify how box-1 creates the particles with a birth texture. Does it spread the number of particles specified in Quantity:amount across the entire surface, and then only actually create particles when the material is suitably white? eg I have amount set to 10000, but the plugin only reports a total amount 1740 particles. Is the number specified in Amount limited by the pflow system parameter upper-limit? or does that only apply to the number of particles actually created? Thanks for your help. Oh, is this the right forum to post in? It seems awfully quiet around here!

Topic  1727  PFlow Tools for Spiral Movement?
I have created a loft, cone-like object which, for purposes of discussion, we'll call a tornado shape. I can animate this object and change it's shape/movement, etc. I would like to have particles move down the length of the cone as they rotate around that surface resulting in a spiral type movement. (I have experimented with the Vortex SW but it does not give the precise control that I need so I must use a base object that I CAN control.) I can use a Position Object operator to make the particles appear on the cone surface but I have not been able to find a way to make the particles rotate around that cone surface and also move down the length of the cone surface over time. Are there any PFlow tools that will create this movement on the surface of the cone object? Thanks!

Topic  1722  Pflow Q:How to complete delete a pflow with maxscript?
I'm trying to delete a pflow by maxscript. but so far I always found some nodes are still live in the scene. here is what i did. pf is the particle source.

Topic  1715  controlling people in pflow
Hi, I need to do a crowd simulation of a large pedestrian flow at a traffic light system. There's at least 8 main paths they will be walking along and can cross in different places to get to different routes (diagonally and laterally). I need to have all the people walk along the pavements and stop when they get to a red light, wait for the green light (there's a set cycle with some going green at different times) and then randomly go down different routes. so... in pflow can I change a point cache file or bip file on a different event. maybe by the script operator? so I can go from a walk to a stop to a walk, while aiming for a target. If I cant change either of these is this going to be possible? Any suggestions apreciated Thanks very much Nick

Topic  1714  really heavy memory on find target + shape instance?
Hi Folks, i've got a simple enough scene with some animated bird meshes taking off and changing to a looped bird cycle with a find target too.

Topic  1654  contraining pointing with SpeedBySurface
Hi I'm trying to get a bunch of particles to orbit a sphere. Satellites around the Earth. I'm using SpeedBySurface to move them round a larger sphere but it's only half working. Here are a couple of questions I have .... 1. Increasing the speed in SpeedBySurface sends the particles away from the surface. I'd like varying speeds. Is there no way I can constrain them to the surface? 2. I'd also like the particles to point towards the centre of the sphere. A Rotation operator set to SpeedSpaceFollow does it, but the movement is jerky as partices move from polygon to polygon of the target object. Is there another way to do this? Or a way to smooth out the movement? Thanks Mark

Topic  1516  Image of a character should break up into particles
I have an imagesequence of a radio play tooncharacter. The clients idea is to let him get created by a bunch of covers flying from out the camera into the scene. We reversed the flow, so now the character break up into praticles. They pass several targets and fly to the camera. this will be reveresed in post at the end again. The problem is: The material of the particles should blend from the character to the covers. We have a charactersequence already assigned to a material and we have a Mat with many Submaterials (different covers) How can I assign sticky UVWmap to the particles my char is breaking up to, so it looks like the character itself will breakup? In the end the particles have to be quads for the covers, so blow up a mesh is way problematic. I tried a mesher with a cam mapping, but hence this mesh is recreated every frame, the UVs are not sticky. Help! Thanks Michael, (NOT owner of any box) Edit: (max2008)

Topic  1485  PFlow Ghost Association?
Oleg, PFlow in MAX10_32 I created a simple PFlow where I had a PLANE object and in the PFlow, I had a Position Object operator to make the particles created on the plane object. I also had Density by Material in use. All was well and the particles were created where desired. Then I realized that it would be better for my object to be a cylinder instead of a plane. The plane object was on one layer so I created a new layer and created a cylinder on it. I then went to go re-assign the Position Object operator to use the new cylinder and I removed the plane object from the list. The particles were showing in the viewport as still being in the area of the plane and not the newly assigned cylinder. So I hid the plane layer and the plane and all particles disappeared (even though the PFSource resides on a different layer). I could not get the particles to show on the cylinder no matter what I did. But when I unhide the plane layer again, both the plane and particles are shown but now the particles fill the circular shape of the cylinder instead of the square shape of the plane. But they will not be shown or rendered unless the plane layer is unhidden. I then deleted the Position Object operator and added another. Still, the particles are only shown if the plane layer is visible. Any idea how to get the particles to only be shown when the PFSource is visible and not on some object that was previously assigned to the Position Object operator? Thanks!

Topic  1479  Timing: Randomizing the occurance of muzzle flashes
Hello All, I'm fairly new to PF so let me know if I should be googling a different term or looking through the help file for something specific. Also, I am using Max 9 (no service packs) and have no plugins installed for pf. The preamble: I have muzzle flashes that I've set up using a standard flow and linked the direction away from the nozzle using a speed of 0.01. I then create copies of the flow and attach each copy to different nozzles. This allows me to link the PF icon to the muzzle and always fires in the right direction and I can control when they start and finish firing for each gun. I have animated the muzzle flash with three pieces of geometry that scale up and then scale back down over a few frames. The Question: I want to have multiple guns firing at the same time, but they all seem to play back the muzzle flashes in sync. I've tried setting the births to start at different times, increasing and decreasing the rate of particles and changing the seed with no luck in changing the overall timing. Is there a way to offset their births so that they look like a random scene of muzzle flashes :) rather than synchronized yahoos :). Or do I need to create several animations and each pf needs to get its own anim? Thanks in advance, Jason

Topic  1438  Using Pflow to create city - real world mapping question
Hi, I've been trying to use Pflow to create an aerial view of a city, the theory being that it might be less memory hungry than, say Greeble. I have been trying to use real world mapping co-ordinates on the textures for buildings so that windows stay a consistent size, regardless of the size of the building object. I'm a little hazy on how real world mapping works, if using that means that unique UVs are store per object (meaning that they are no longer instanced). Anyway, I don't seem to be able to get Pflow to recognise the real world mapping, so the windows scale in relation to the size of the particles. I've tried using the mapping object from Box #1 and picking another box with real world mapping applied, but that didn't work. The standard mapping operator doesn't mention real world mapping either. Of course I could snapshot the resulting particle system, but then that I lose the advantage of instancing. Any suggestions are welcome. Thanks, Steve

Topic  1436  Why do static particles need to be calculated every frame?
I have the simplest flow possible, render>birth>position icon>display The birth start/stop is 0. If i set the timeline to be 4000 frames and then scrub the timeline it stutters as pflow is calculating a little bit of something. Why is it havn't to calculate stuff when nothing is moving? If i add a cache then the problem is alleviated but it seems to need to cache every frame which results in a large memory foot print for static particles. I assume this is normal behaviour but why is this so?

Topic  1341  weird spawning behavior
I noticed this weird behavior inside a standard pflow. I’m guessing this is just a bad side effect of the pflow architecture. Basically it looks as though the first spawn is adversly affecting the behavior of the second spawn. Both spawns are identical yet they yield different results. The second spawn only processes every n-th particle depending on the speed of parent. [url]www.blipland.com/temp/badspwnning.max[/url] I'm usually rocking the box#3. But I love the spawn by distance, so I went classic pflow when I ran into this little glitch. Cheers, Ben.

Topic  1338  Maybe I'm doing something wrong (cache)
I recently purchased the stand alone cache program. Perhaps I am applying it wrong, but it seems quite a bit slower than just using PF by itself. My animation is 1700 frames with particles from frame 1240 -1700. Any modification and the update takes over an hour for the Cache plugin to recalculate. It is actually faster to just render out (we have a render farm) as opposed updating the plug-in. I didn't want to post on the CGtalk forum so as to cause a negative impression of the product. We have added the express save already. Thanks in advance for any advice. David

Topic  1318  Sub-object material IDs not being obeyed
Hi all, I have a new problem and have been unable to find a solution using the search function. I really hope there is a solution & I just haven't been able to find it! So.... I am simulating a chemical reaction with various molecules. In brief, I have a single animated mesh in which different parts move around to create different compounds. This mesh is my instanced object & the animated changes happen at the correct time in relation to particle age. So far so good... I also need the different parts of the mesh to have different colours which change as the different compounds are created. I have done this with a gradient ramp mapped to particle age. I have 2 different sub-object materials that both change colour over time. This works great when the whole of the instanced object has the same sub-object ID but when there are 2 IDs(as I need) then PFlow applies each complete instanced object one of the 2 sub-object materials instead of applying the correct Material ID to the Sub-Object ID. I have noticed a few points: 1. Using Material Dynamic with "Assign material ID" checked I get the results as listed here. 2. Using Material Dynamic with "Assign material ID" unchecked I get the correct distribution of the Material IDs but the Event age is taken instead of the particle age. I hope this has made sense to someone & that it is solveable (or that there is another coolway to do what I want!) Btw... is it possible to stop the Flow reassigning Material/Object IDs every time a particle dies? Thanks! Elliot

Topic  1215  PF Speed in MAX9_32 and MAX9_64
Oleg, This is a part PF and part MAX9_64 question. OK, today I installed Box3 on all versions MAX8, MAX9_32 and MAX9_64. As part of verifying the authorizing, when installing in MAX9_32, I quickly created a PF Source spewing some particles over 100 frames. I then added the Disk Cache operator just below the Render operator. I updated the Disk Cache and afterwards scrubbed the timeline. The interaction was fast as desired and I was pleased with the apparent speedup. Then I went to click the Play button to let the timeline play back. It played well in most spots but there were 2 or 3 spots where it hesitated and stuttered. Not really knowing what to expect, I just made note of it. Then I did the same thing in MAX9_64 only I then went into the Disk Cache operator and picked the previously saved Disk Cache file. I hit Play and it played back realtime with no apparent hiccups (or if there were any it was very slight) but the visual difference between MAX9_32 and MAX9_64 was very apparent. My question is, I thought MAX9_64 would only provide improvements in handling large scenes... not make anything particularly faster. Yet PF (in this instance seems noticeably faster). This got me started thinking whether there were other advantages that might lure me to move towards 64 faster for production (I was planning to just use MAX9_32 for the time being). Why is PF faster in MAX9_64? This is on a Dual Quad Core system with 8G RAM, x64. Thanks!

I don't post as a Bug, but maybe it is one ?? :-? http://www.b3d-animations.com/tmp/small_flow.jpg regards, Bandu oh... this recovery event seems not to be a copy of my birth event I've replaced, born timing is different...

Topic  1168  Recieving Rotation/Orentation from Polygon Face
I'm animating a vine using a cylinder with a taper and then using a path deform to animate it. I was hoping to add Thorns around the vine using PFLOW. I can't get them to face out along the cylinder and then when I animate the rotation on the Path Deform they stay fixed at there initial rotation, I need them to be fixed but rotating to match the orentation of that polyface? I have Box1 and using max9 at the moment, is it possible? or is it a Box3 upgrade (I'm hoping it is .. I need an excuse through work to buy it :D) I hope I'm saying this correctly .. Thanks in advance.

Topic  1062  UOmniDeflect with deforming object
Hi, I've got a plane with particles sitting on the plane vertex positions. I want these particles to react to a torus scaling up (by animating its radius), moving into another particle event when that happens. I've set up my scene with an UOmniDeflect, and a Collision Test and I was hoping that would trigger the particles. But it seems like the Collision events wont react unless the deflector or the particles are moving. Is that correct? Or can they react to changing meshes as well? Rune

Topic  998  Animated Rate : Out of Range
I'm posting this to autodesk as well, but I just wanted to check: Both Max 8 and 9: 1) Create a new scene 2) Expand timeline to 1000 3) Add a standard Pflow System 4) Change [i]Birth: Emit Stop[/i] to 1000 -> Particles flow for entire length. 5) Change [i]Birth : Amount[/i] to [i]Birth: Rate[/i] 6) Animate [i]Rate[/i] from 60.0 @ 0f to 0.0 @ 30f - > Emit stops at 30f as expected. 7) In Curve Editor, set out-of-range interpretation to [i]loop[/i]. The effect should be a 'gushing' every 30f. However, you only get this during the keyed frames. 8) Change the key at 30f from 0.0 to 5.0. Scrub the timeline. The effect is as intended until ~ 172f where flow stops for no reason. Edit: A workaround is to animate a spinner or custom attribute as the rate and then wire the parameter to the rate. Really weird. Khye

Topic  984  Particle Age map...
Hi everybody, I'm having trouble with the particle age map and I don't know if I'm doing something wrong or if something's wrong with my max. Basically I make the simplest possible flow - just particles moving away from emitter with slight divergence. I add a material Dynamic and use a material which has particle age map in diffuse slot. Render - no colour change, just all particles as color #1. I understand you need to delete the particles at some point to create their "lifespan", so I added an age test fed into a delete. No effect on color. Also tried using the other material operators - no luck. What's going wrong? May just be something simple that I'm overlooking but I can't think of anything. Help please.... Z.

Topic  936  Particle Attachment / Linking
Hi guys, i hope someone can help me with this, i'm sure it's quite easy to do but i am a bit stuck. Basically all i want to be able to do is link a Pflow to an object. the basic effect i want to achieve is to have particles that are locked to a surface/object (like the lockbond) but that still operate in their own space and react to forces etc. Imagine a static plane with 10 particles on it. now imagine all those particles doing something on the surface (moving / bouncing / whatever). now i want them to do exactly that, but linked to the plane. so i can animate it and the particles will still do the same movement, keeping their original movement. I have tried the lock/bond and link to emitter options but nothing gives me the right result. i can cheat it in a number of ways but really want it to be setup correctly. I thought i could do it by having a clone of my plane as a reference. if i could reference each particle to the UV's of the first plane(static) and then offset them by the difference of the UV's of the new plane (animated). Any help would be really appreciated. Cheers Matt

Topic  891  Event to Event Particle ID Changing, Idee...Problem
Hy, I am new to this forum, and at first: Hello to all of you ! I currently became stuck in an approach to generate nice looking cigarette Smoke based on the idea of "particle driven surface animation". My attempt is to animate Pflow particles and attach each vertex of a plane to each particle. Using the turbulence in the wind spacewarp, the particles become nicely distorted. Currently i am using mesher and pointcache to convert the particles to Objects the SkinWrap Modifier can access. This Modifier is used to "bind" the Plane Vertexes to the particles..Well, its a bad workaround but it works. Only Problem is, it only works with one single Pflow event, because the ParticleMesh (a single face in my case) is renumbered everytime, when a particle is send to the next event. Which means that, the SkinWrap modifier will become heavily confused...ends up, with a completely distorted mesh. So i have to controll all particle movements with animated forces, which is quite "oldschool" and will never end up in a nice animation. The plane sticks to my particles and becomes really nice distorted. Adding a relax and Turbosmooth will make it look really cool. Using Falloff and Texture Shaders, you can get pretty nice smoke. -> in a still.. because i cant use send-out events, etc.... So, my question is, if anyone has a idea, how to solve this problem...or, if Orbaz Tools may have a solution for this... Thanks so far, Regards, Thomaskl http://www.thomasklieber.de Here is a rendered still that you can get an idea of how it might look: [img]http://www.thomasklieber.de/Rauchstill.jpg[/img]

Topic  872  A standalone Pflow
Hi, I was wondering if there was any advantage to having something like Pflow as a standalone app as well as a plugin? Obviously you wouldn't have the overhead of Max running, and it could be streamlined for particle use, maybe it could then be piped back into Max for rendering or even have a renderer built in? I guess the main thing would be getting mesh and animation data in, and replicating the various space warps - or does this sound like more trouble than it's worth? Thanks, Steve

Topic  859  Lock/Bond type effect in Box3
I'm looking to re-create a portion of the Lock/Bond operator in Box3 to get a "skin wrap" type effect. The problem with Lock/Bond is that the object must have extremely high tesselation when particles are far away from the surface, presumably because the normals of the surface are evaluated only at the vertices. I can get the closest point, and the distance to that point, and the normal of that point, but I can't seem to get anything that will give me orientation to the normal. As in tangent/bi-tangent. Is something that would allow me to position a particle relative to a animated surface point?

Topic  858  loading disk cache
I'm having a bit of a problem with the disk cache. Maybe I'm not understanding how this is working, but I've saved out a .pfc sequence, but I can't figure out how to load it. There's no UI item for locking the cache or setting to to read only, and I can't seem to be able to get the cache to actually load. When I get to a frame that has a cache file valid, all my particles disappear and are not replaced with the cached ones. Is there a way to load the cache from one system onto another? I'm thinking maybe like the Initial State operator. I have a file where the particles are evaluated, and I want to put them into a scene that I will render from, but it's just not working. - Chad

Topic  856  Particles & Image Motion Blur
I am trying to understand the proper Image Motion Blur usage here. I have an animation of a race car going off the track then hitting the wall. All is setup as desired and as the race car skids across the grass opacity mapped particles are emitted as dust. When the car hits the wall, simple object particles are emitted as debris. The dust rises and chunks fly. All scene objects are set to render with Image Motion Blur. Problem is, when I applied the freebie Camera Image Motion Blur to my events cuz I thought I should, the resulting motion of the particles is wrong compared to what I setup visually originally. The dust barely rises therefore the opacity mapped particles stay low intersecting the ground plane showing artifacts of this. The debris particle motion is also wrong as it flys a small distance rather than the large distance that was setup. The question's are: 1. Do I actually need the freebie CIMB on? Would it render OK without it? 2. If I do need it on, since it alters the setup motion, do I need to drastically increase those motion values in order to get back to what I had setup originally? Thanks!

Topic  836  Simcloth and Particle Flow
I have been doing some R&D with simcloth and find it to be an awesome candidate for experimentation with particle flow. When you connect a simcloth sim as a position object combined with a lock-bond you can generate all sorts of secondary motion effects (especially with object motion blur). Now it is cooler out here up in Southern Ontario, Canada (actually way south of Toronto, Montreal or Boston, USA) I will be putting up some tuts I also found some very interesting other uses for Initial State! Once our Avolution trade show demo is done for November 15th I will have more time after work (in the darkness known as a Canadian autumn) to post these at Orbaz. I have been watching of late; but I have been learning something called a Mac G5 (and Final Cut Pro, Motion, DVD Studio etc) so the time for particles has been less.

Topic  835  Particle Age Material
First off I'd like to thank Oleg for such a wonderful particle tool, I've been using an in-house proprietary tool to create particle effects for the last year and switching over to Particle flow is like coming from a wasteland into a lush orchard. Now on to business... My goal with this scene is to spawn a variety of arcane symbols that drift up then fade away before they expire. I painted a single texture map and used a mix of cropping/placement and multi sub object materials to divide the various parts. In my file are two examples of attempts I made with the materials in order to set something up that can fade over time using the Particle Age Material. My dilema using dynamic material operator is when I switch on "reset Particle Age" the desired fade out occurs, but then it treats the set as an animated texture swapping my little symbols at random. When I use sub- Material rotoscoping the various material ids are distributed well, they dont shift anymore but I lose the fade. I hope my ramblings make sense, I'm up late trying to complete a project but have found myself hitting a wall. Any ideas?

Topic  800  Lock/Bond and rotation "snapping to" surface norma
I was playing around with the lock/bond operator, as a means of getting objects to travel around on the surface of an animated object. It's working pretty well, except that the rotation of the particles are prone to "snapping to" in order to match the normals of the faces they're travelling over. There's an example here: [url]http://www.adamwatkins.com/LockBond_snappingRotation.zip[/url] I would've thought that increasing dampening would decrease the sharpness of this "snapping to" behavior, but I haven't found any settings that work yet. Any thoughts?

Topic  792  Strange PFlow/Reflection Problem
I have a bizzare reflection problem that seems to be related to PFlow. I have a camera that flies down to ocean level. The ocean is simply a plane object with a Raytrace Map for reflection. There are PFlow opacity mapped (special shape plus) clouds up in the sky which the camera sees a little bit of as it flys almost straight down towards the ocean. When it gets to a certain level, it has already flown past all the clouds but it can still see the clouds in the reflection of the ocean. (I should note that the camera doesn't fly directly through the particle clouds but rather there is a strategic hole that it flys down through so the clouds pass nearby). The problem is after rendering this, during the whole flydown sequence, there is this wierd flashing or strobing that seems to occur at regular intervals (about every 30 frames). I have isolated this to one PFSource of clouds (there are 2 sets of clouds in the scene). After the camera is below the clouds and looking at the ocean and seeing the cloud reflections, it's as though some cloud particles disappear for say one frame and then reappear because the reflections disappear and then reappear. I have looked closely at the PFlow clouds with particles 100% visible and can't see any disappearing or reappearing. But when I hide the PFlow clouds entirely and render a couple of comparison frames, the problem goes away so I know it is related somehow to the PFlow clouds. Earlier, I was experimenting with the Camera Cull operator but then later realized that the out-of-view clouds were disappearing from my reflections so I removed it. Could this be somehow having an influence even after it's gone? Thanks for any ideas!

Topic  786  Positioning Particles Across a Multi-Element PosObject
I have a mesh consisting of a bunch of elements which represent crude clouds. When using the Position Object to position particles across these cloud mesh elements using either vertices or surface or whatever, particles are not positioned on all clouds until I cross some numeric threshold of particles. For example, if I set the birth rate to 100 particles, the particles are bunched up on some clouds and none on other clouds. If I increase the rate to say 500 particles, all cloud elements do get particles but there are still a massive number bunched up on some clouds and few on others. I would like to have one particle per cloud until all clouds have one particle then start adding the remaining particles to the clouds in an orderly fashion. That way, all clouds are 'bulked up' in an even fashion. Is there a way to do this with PFlow or Box1? Thanks!

Topic  784  Sync Material to Particle Age
Hi. I have a situation where i have animated the position and colour of the flags on a radial gradient ramp to get the effect I am after BUT it wont sync by particle age. Each particle uses the material based on absoulte time I've tried using a particle age map and having a start, middle and end version of my gradient ramp as sub maps of the PAge map but all this does is animate between each as if they were a static image rather than moving the flags like I need them to. i am using pflow with a material dynamic I have done some looking and the only 'sync by particle age' option i know of in a map is in a bitmap which doesnt make the animation very procedural if i have to keep rendering out a gradient ramp to use in the bitmap slot EDIT: I've now experimented with rendering out the gradient ramp map to a .mov so i can use the 'sync by particle age' option within the bitmap's time rollout but it is STILL animated by absolute time! Any help would be much appreciated - maybe a script somewhere does this ???

Topic  778  Linking Pflow Sources to PointHelpers - slowdown?
From time to time I've come across a significant slowdown when linking a pflow source to a point-helper. Are there any specific do/don't with regards to linking pflow stuff? Earlier today I linked several pflow sources to unique point helpers. I then took each respective pointhelper and linked it to a root node. Animating these helpers seemed much slower than if I simply animated each of the pf sources directly. I looked around the forum and the docs but haven't come across anything yet. I have again relinked pflow sources to unique point helpers, but did not link them all to a root node. This seemed to keep the speed acceptable. I wanted to be able to link so that I could exactly track the motion of a character, but the speed was not acceptable. thanks - .jeremy

Topic  775  Repeated crash at rendertime.
Hi all, I'm having an issue here with Max crashing when I try render a pflow scene twice (i.e. doing test renders). The first time it renders ok, then when I hit 'render' again, it goes through and meshes my pflow, but when it's time to actually render the tiles, it crashes. I'm rendering with Mental Ray and am using Box#3 (Cache Disk operator and a couple Dataflows). I've been able to narrow it down to absolutely being the pflow, since when I render without it, it goes along fine. So, does anyone have any tips on how to go about "debugging" it and trying to get it so I can finish this project? -Chris (mods: sorry if this is in the wrong forum--this kind of a general particles question, but also involves Box#3)

Topic  773  Particles Collide with Stand-off Distance?
I am creating ocean foam where the ocean meets the beach and I'm trying to use V-Ray to render. I have an Island object that emits the particles from the selected faces at water level and immediately after the particles are emitted, gravity pushes them right down onto a flat plane deflector object with high friction and they stop. The particles are opacity mapped Particle Plus cubes and I have an animated scale which basically flattens the cubes in World Z with a constant value and varies the XY so the particles grow/shrink over time. The end visual result works well for my needs but there is a problem (naturally!). Because all the particles are the same thickness in Z and because they overlap one another, well... they overlap one another! This is not a problem in itself as the scanline renderer renders these overlapping particles just fine. But V-Ray currently has a bug with regard to rendering these opacity mapped, overlapping particles properly (as the scanline can do). I am trying to see if I can find a way to have the particles not overlap in Z when they collide and stop on the deflector. In other words, to have one particle stop on the deflector and the next adjacent particle stop above the deflector, the next on the deflector, the next above the deflector, etc. So the end result is particles that are offset from each other and therefore not co-incident so V-Ray will be able to render them properly. Is there any way to create some kind of stand-off distance for the deflector that would alternate particle position in Z? Thanks!

Topic  725  Z depth intersection fade? (3dsmax)
Hi, Does anyone know of any methods of using the zdepth in an opacity map material. Basicaly what I need is a way to fade the intersections on facing transparent particles. In more modern computergames pixel shaders can be written that use the zbuffer depth to change the opacity of a pixel that is about to be drawn. As a facing particle intersects a solid object the zdepth of the existing pixel becomes closer to the zdepth of the pixel that is about to be drawn, as the values become closer the output pixel becomes more transparent. The end result being that there is no visable hard edge when a facing particle is intersecting a solid object. Does anyone know of a way to do this preferably with the standard max renderer, or if that cant be done there can it work with mental ray? Is there a plugin that allows a user to write a pixelshader within a standard max material? Thanks FXmonkey

Topic  693  Map affected by space-warps?
Hi, this is only indirectly linked to particles, but I thought I'd throw it into the ring. Does anyone think it would be possible/feasible to have a map which is affected by space warps, e.g. Wind Turbulence/Drag etc? I thought it would be quite cool to have a volume light/afterburn combustion effect which distorts based on space warps. There is a Wind Daemon in Afterburn but it doesn't have turbulence. John Burnett wrote a visualiser object which interprets space warps, but I was thinking more along his warp texture which pulls and stretches maps along the force of the influence of the warp. Any thoughts? Cheers Steve

Topic  687  A couple of questions about animated textures
Hi, I've been experimenting with facing particles and animated textures for water spray. I've set up a couple of sub-materials with different IFLs, but when I add a delete operator, the animation seems to flicker wildly towards the end of the animation. If I remove the delete operator it's OK. Any ideas? Originally I thought it might be down to one material using a different number of frames to the other. Should the dynamic material be OK if the number of frames differs from material to material? Thanks, Steve

Topic  661  Particle Orientation Problem
We have a Geosphere which moves upwards through a plain, starting completely below and finishing completely above the plain. We are triggering animated particles on the surface of the sphere so they start to grow outward from the surface as soon as the bit of surface they sit on touches the plain. The growth is perpendicular to the surface normal. It works great for the particles on the upper hemisphere but those on the lower hemisphere grow from the surface towards the centre of the geosphere (ie they grow the wrong way). We have tried selecting the lower hemisphere and flipping the normals, but this has no effect. Oleg, we've sent the scene to the upload email address for you to look at. If anyone else knows of this issue, any help would be much appreciated. Cheers Z.

Topic  655  PF script UI's
Hi. I'm creating a PF script that manipulates particle values over time. Basicaly particle components like scale, wind resistance, particle age time warp (for animated textures) and a few other things. I have already writen code for an interpolation function which operates using set data which I hope to eventualy create from a graph, simalar to those used in the output section of materials. What I need help with is creating a UI for PF scripts, I understand that this type of script is procedural but is there any way of having part of a script dedicated to a UI for creating data that would be used within a procedural part of the script? Is there any examples or tutorials for creating PF scripts with UI's? Ive done lots of standard utility MaxScripts with UI's in the past but I'm not sure of the best way to do this for PF scripts.. or if its even possable. One way Ive considered is having a seperate maxscript utility that allows a user to edit the graphs storing the data in either a blank anim track or as userdefined data on the PFsource object. Then the PF script might just use whatever data is there. Idealy though I'd like the PF script to do all that by itself. Any help would be apreciated. And I'll be sharing the script when its done for anyone that needs that kind of control over there particles. _____________ FxMonkey _____________

Topic  651  Growing particles with Birth Texture
Hey all, In my never ending quest to have floating particles form a word from another word I was wondering if the Birth Texture could be used. I was thinking of possibly have a texture animated of the word from nothing and have it reveal more and more of the 'white' of the word so over 100 frames or something a word texture appears and the birth texture would be used to map the particles to the animated texture as it reveals the wording? Does that sound like something that could work and if so what would be the process to actually implement it.. i.e. the animated texture etc. Many thanks.

Topic  573  Please help!!-Stop Gradually Then Speed By Icon
Hello everyone, I need some help with some particles that are very bold. I have a system that runs along a speed by icon (which follows a path to make a trail) into a deflector (for a collision test) and starts a new event which then runs into another deflector and once more. So thats three deflectors and one pflow. Now I 'stop gradually' one of the events at around frame 325 so that half the particles go off and do their thing while the other half stops in its tracks. Now I need the ones that are stopped to follow a new path but when I create a new event from the particles that are stopped by the stop gradually test they move in a group in way that resembles the new speed by icon which follows a new path. I mightn't be making much sense so please take a look at the two images I posted. They might help a bit. If anyone has any idea what I'm talking about please reply.

Topic  514  Killing Particles
I have a flow where I have particles (blood cells) flowing through an artery. There is a render event and blood cell event: RENDER BLOOD CELLS Inside the blood cells event there is a 'Collision' operator which looks to a UOmniflector>mesh of the inside of the artery. The emitter is inside the artery and as the particles are emitted, they travel through the inside of the artery and bounce off the artery walls as they should. At the end when the particles leave the artery, I want to delete them. I have created a box, and a UOmniflector>box. I added a 'Send Out' operator to the bottom of the BLOOD CELLS event which goes to another event with a 'Collision' operator pointing to the box UOF. The output of this 'Collision' goes to a 'Delete' event. Problem is, my order must be wacked because I can't get the particles to delete. Can someone tell me the proper order/placement to first collide with the artery walls then collide with the kill box to delete the particles? Thanks!

Topic  503  Box#2 and such
I've got so many questions about the fate of Box#2 that I have to confess - I lost it playing poker in Montreal... But seriously now :) We gave the development priority to [url=http://www.orbaz.com/forum/viewtopic.php?t=464]Box#3[/url] in order to have more build-in functionality in Box#2 later. You may know about the "script wiring" ability of some Particle Flow operators. Namely, you can right-click on Force or Keep Apart operator in Particle View and select 'Use Script Wiring' option. As a result, the operator gains additional rollout with script wiring options. For Force operator, for example, you can use Script Float channel to define individual influence for each particle. The problem with this "script wiring" approach is the scarcity of the script data channels - you have one of each Integer, Float, Vector and Matrix data channels. Therefore, with the complex logic of particle interaction you run out of the data channels pretty fast. You can stuff 4 vectors or 12 floats into the matrix channel but still... [url=http://www.orbaz.com/forum/viewtopic.php?t=464]Box#3[/url] resolves this issue completely. You have unlimited number of data channels, with the variety of types: Boolean, integer, float, time, vector, quaternion, matrix and more. The data channels are created by the 'Output New' sub-operator, and then they can be used by other sub-operators. These data channels can also be used for information transfer between different Data Operators, and even between different particle systems! All in all, we thought that it would be nice for the operators in Box#2 to work with the custom data channels in the manner similar to the "script wiring" in the standard Particle Flow. But for that the [url=http://www.orbaz.com/forum/viewtopic.php?t=464]Box#3[/url] has to be implemented first, as you can see. Thanks, Oleg B. P.S. This is the info that was first given at the CGTalk forum earlier. But since not too many people went through the announcement there, I copied the message here.

Topic  363  ESC key doesn't work after making a preview
I have sort of a stupid problem here. Not sure if it's max or pflow related, but here goes: I have a scene with 750 frames and particles being affected all the way though. Nothing fancy, but if I click the time slider from frame 0 to frame 750, naturally, it will take some time to get there. When I make a preview, and max is done generating it and playing the animation, and I click the max window to go back to work, the window won't activate, but I can see pflow calculating the particles up to the frame max is currently set on - which happens to be the last frame of the animation.. due to the preview I just rendered I guess. And the ESC key has no effect because the max window is not selected. So I'm left with the choice of either killing the max process or waiting 5-7 minutes for it to complete (in this case.. could be considerably worse). I've tried using task manager for "bring to front" and "switch to" with no luck. Any bright ideas? It doesn't happen _everytime_, but when it does I feel like biting off a finger. :/

Topic  295  Particle per vertex
I working on an animation where I am generating floor tiles from instanced geometry, and using a collision test to trigger the tiles to flip over. The idea is that as I sweep a deflector through the tiles they rotate in sequence to reveal their undersides. It's all working fine except that I need one particle to spawn at each vertex, currently even with seperation turned on I still get overlaps on some vertices. For example, the distribution object has 36 vertices but I have to spawn much more particles than that to get at least one on each vertex. Our TD wrote this birth script to overcome this issue, and it works perfectly until the deflector touches the first particle and causes Max to crash: [quote]on channelsused pcont do ( pcont.useposition = true pcont.usetime = true ) on proceed pcont do ( meshobj = $teapot01 --your mesh here! meshobj_numv = meshobj.numverts for i = 1 to meshobj_numv do ( if ((pcont.numparticles()) <= meshobj_numv) do ( pcont.addparticle() pcont.particletime = 0f --your start time here! pcont.particleindex = i pcont.particleposition = (getvert meshobj i) ) ) )[/quote] Is there any way of spawning a single particle per vertex, and failing that is there anything obvious in the script that would cause Max to crash? A JPG of my flow is here: [url]http://gd5.cn/stuff/pflow.jpg[/url] And I have a test render here that shows the effect: [url]http://gd5.cn/stuff/flipping.mov[/url] Overlapping particles show up as opaque. I can't leave the overlapping particles in the final shot as the final geometry uses refraction and, even without that problem, I am using an age test to flip each tile randomly a few frames after the collider hits them so the overlapping particles flip out of synch and intersect..

Topic  220  What I like about the particle flow experience
1)Once you learn particle flow, you can make cooler things as well as make them faster (something the boss likes) 2)The event driven nature of the beast, allows a more "what if" type of changes (it's been very rare for me to "one time" a particle flow setup, but man, when you do...) 3) I want to bypass "reactor", which in IMHO is conter-intuitive and through scritping, birth scripts and pos objects in event driven scenes, make reactor seem redundant! Weekend time........logging off :D

Topic  219  Is Custom "Reset Particle Flow" Possible?
When you go to Utilities\More\Particle Flow Utility\Reset Particle Flow I was wondering if there is a way to write a custom scene that this calls. For example my 3dsmax.ini and the Reset Particle Flow do not match as my 3dsmax.ini has the following turned off Depot Desciption Use Dynamic Names and Track Update\Particle Count turned ON just curious, maybe a maxscript?

Topic  212  beginning
My learning process w/Max ,may be out of the norm,as I consider myself fairly adept w/static compositions...decent w/the material pane,lighting etc....yet entirely novice w/scripting and dynamics...just purchased this plug from TS,and I'm really disappointed w/the training videos...I mean they obviously cover some good content-I watched them all...but they left something essential for me-how to get out the gate w/the plug...I mean I do have it initialized,triggered something that prompted me to enter the reg-authorization number...but the first vid-which purports it will tell me "where to find things" pops a panel-in which all this scripting and video content operates called "Particle View"...His arrow is down on his perspective pane-and suddenly out of nowhere this panel emerges...Think of how frustrating that is-I can't follow along at all without that.. Is there a pdf? Heretofore whenever I have needed particles-which is often...I've made particles in Discreet's Combustion-either as targa trans for postwork...or directly as postwork on image in Combustion...see gallery of "gmonkai" at deviantart.com...can do all that but cannot open this "particle flow" panel everyone is using for this stuff...please someone help me out? Also to whatever particle wizard or wizards deign to answer these novice questions...I loaded some presets -for example "the nebulae"...what do I need to render something?lol!..have added lights and material,and no go...Help,please? Will post my rating at TS soon... It's driving me nuts...When I write Photoshop tuts-I start with "baby step" assumptions-so they may reach everyone-and not subjective tech adepts only...I watch this video and he pops the panel magically from the rocket a second time...I peruse them all,I peruse this site...nowhere is an ample demo on just how to open this panel-so a new user might get out the gate... I expect big learning curves..but the omission of basics is just alenating... okay,got view...to any checking this site on same prob:Create panel > Geometry > Particle Systems > Object Type rollout > Click PF Source. > Setup rollout > Click Particle View (or press 6). okay,anyone responding please get me to texturing,and lighting...or whatever will make these visible in render.. Well,as now I've fiddled hrs away-I'm going to Combustion for the particles I need for current workflow...If anyone will condescend to explain-how do I get a material on this nebulae...I have added "Material Dynamic","Material Frequency","Mapping" and "Mapping Object"...where do I insert-in third subpanel?...I have added lights...nothing shows up in render...people need a pdf for beginning on this stuff bad...get me out the gate reasonably-and I'll write one...

Topic  138  Problems with scaling facing particles
As I wrote already in the discreet support forum, I can't control the size of facing particles with a scale op and I still do not get what's wrong. No matter what size I set for the particles, as soon as i place a scale op into the event, they shrink to a minimum birth size (even with scaling 100%) with normal particles it works as you should see in the pic. tetra particles are 3 units big, facing particles are 3.000.000 (!) units in size.

Topic  130  Copy Lists
I don't think I have seen this posted yet. And if there is already a way to do this, PLEASE tell :) It would be nice if there was a way to copy and paste one list to another. For example, I have a long list of objects in the Position Object operator and I want it in the Lock/Bond or Speed by Surface operators. I think it would even be cool if you could instance those lists.

Topic  120  PF, frame rates, and integration steps
I was thinking of trying an old film trick and doing some of my animation at 120 frames per second in max, and then dropping the frame frame down to 30fps in post. Now, if you have an integration step of say render =1/2 half frame at 30 fps, does that mean the integration step would have to be 1/2 x4 or 1/8 frame, or is PF frame speed independant?

Topic  119  Storing mapping coordinates in shape channel
Hello, I am currently generating mesh and UV mapping of that mesh on the fly for each particle in a scene and I have it set up so that the mesh generation occurs once on the first frame and is then stored in the shape channel. Do the mapping coordinates get stored with the mesh as well? I noticed the ".useMapping" flag and was wondering if perhaps the mapping was a seperate channel. I can get it to render fine if I generate the mesh and UV mapping on every frame, but when I set it to only generate mesh on the first frame, I get a "Missing Map Coordinates" error when I try to render. Thank you very much for the great support. Nelson

Topic  100  Using PF BOX #01 as Secondary Motion for Reactor Scene
The following is a quick and dirty scene I fabbed up after work that shows you can use the Particle Flow Box #1 Tools to add secondary motion information to Reactor scenes. Layer <HIDE> contains the original Reactor created geometry Layer <0> contains the pflow objects There are two flows ..the first one is a birth script with a global recursive LOCK BOND (that is, the lock bond callls the very geometry that is in the birth script boxes2-28... this flow gives primary mirrored animation of the reactor scene. The second flow uses the INITIAL STATE that reads the animtion of the first flow...this is then sent to a local recursive LOCK BOND that acts as a buffer for the geometry that is sent to the SPAWN BY TRAVEL , DELETE BY AGE, and SCALE BY AGE.... If anyone else has any suggestions or uses, please don't hesitate to comment on this scene.... here is the screen shot http://avolution.com/outgoing/GRAB.JPG here is the scene http://avolution.com/outgoing/PF_REACTOR_FX.max

Topic  91  Birth Script Error??
Is it possible to have an error in a Birth Script that causes particle to show up in the Vewport, but not in the rendering? Here is the script...I hacked away at the one that was there, and for some reason I cannot get my head around a way to have the particles spawn at a rate any less then 1 per frame ( I think the script by default does it every 8 ticks or so). So I got it to do 1 per frame and I am splitting only the ones I want (every 5th in my case) into the rest of the flow. If someone could show me the correct way to birth script a frame rates over 1 per frame as well, I would appriciate it. Thanks. But the problem is that they show up just fine in the viewport, butthey dont render. Everything seems to be connected right. I have multiple flows sharing the same Render Operator, and they all work except the ones with this Birth Script (actually the other script is for the left gun). on ChannelsUsed pCont do ( pCont.useTime = true pCont.useAge = true ) on Init pCont do ( ) on Proceed pCont do ( gtR = $'Point_Gun Target_R'.position.controller.position_constraint.weight as array if (amax gtR) > 20 then ( t1 = pCont.getTimeStart() as float t2 = pCont.getTimeEnd() as float if (t1 < 0) then (t1 = 0) if (t2 < 300*160) do -- 300 frames ( for i in (t1/160+1) to (t2/160) do ( curTime = 160*i as float pCont.AddParticle() pCont.particleIndex = pCont.NumParticles() -- last particle that was added pCont.particleTime = curTime/160 pCont.particleAge = 0 ) ) )--End If ) on Release pCont do ( )

Topic  87  So no point rendering . . .
I read about the point renderers in the 'particles around us' section. So since that's unavailable commercially, how do you render things like thin smoke. AB Is great for billowy, dense gas but fails in this regard . . .or else I'm naive about some settings. I saw a good coffee cup animation on CGTalk that had the rendering percent at 1500% to achieve a nice effect and the Box 01 memory clean up would obviously improve performance, but has anyone else found out a method that wasn't so memory intensive?

Topic  79  Combustion and Particle Flow
Last week Avolution picked up a HD editing suite on a Mac Dual P5 with FCP and Combustion. I haven't even cracked open the program yet, but I was wondering if I could render my particles with simple opacitty boxes, material ids etc, and export the entire sequence as an *.rpf and have combustion do all the fire effects, etc right now everything is done in max, but is it much faster to have an external progtram do the post work for particle flow a total newbie to combustion :shock:

Topic  74  Group select and Grp Operators
I love the grouping abilities in Tools#1, they've helped immensely on my current project, but.... I'm not getting results from some of the groups I'm creating and modifiying. Is there a limit to how many will work in a system or event? (Wish: I'd like to see the "Group Selection Operator" be a list - why have only 1 group available per Operator entry? - I've got about 25 of each in one event [GrpSel ops and GrpOp ops]). Also, when I split out this giant event of Grp Selection ops and Group Operator ops into 2 events, only the first event set worked. (Keeping related GrpSelect ops and GrpOp ops together of course). Thanks for any info, - Ron

Topic  66  One particle system triggering another one?
Is it possible to have one pf source "sense" when another pf source has collided with a group select and then have this activated pf spawn particles to create itself. So far I have set up a fragmented text letter "A", the text holds stable for 30 frames and is then is blown by a kaos wind into a group select that references a mesh object (no render) letter "B" This then sends out a spawn and random speed and then the A Event dies by particle age. Is it possible to have Event Letter "B" detect that "A" has hit the group select and then start spawning into the new shape "B"? I am trying to fake a sandblaster, and I hope the answer lies with the group operator, but even after reading the help file this operator confused the heck out of me thanks

Topic  60  K.I.S.S. use for group select and split group
For super quick and dirty looped animations try this. For this example, i will set up falling snow The emitter starts above camera view, and the group select lives below the camera view. Set up about 100 particles over 300 frames. (-300 to 0) Set up a gentle speed 50 meters, variation 25 meters Use a shape plus "square" with mapping on, a rotate set to 90 degrees X, and shape 50meters or so with a variation of 25 meters (these units are TOTALLY dependant on units, and obviously dependant on camera distance, which in my case the target was 0,0,0 and the camera was at 0,-1300,0) Opacity map a snowflake to a material dynamic (just in case you want to run age fades or color changes) Set up a position icon set to allow all the flakes to fall from above camera view (I made mine so it streched about 20% past either the left and right safeframes, and sent it back 500 meters away from the camera Y ) Set up a wind say strength .25 turb .25 scale and other item (memory gone) to 0.05 or so. As the speed allows all the particles to be past the camera after 10 seconds, set up a select group-split group combo to catch all the off-camera snowflakes. Send this to a spawn, delete parent and loop the output back to the input. Preroll the birth from -300 to 0 ,but set the scene length to be from 0 to whenever (you could even set up an initial state, but for 100 particles there is not really any overhead) This way you can rig a 600 frame animation (in my case a "join us for New Years 2005 casino ad") with only 100 particles and this is quite memory efficient and fast.

Topic  59  fragments, stl, birthscripts, and gotchas!
I went back into work tonight to try and debug a scene that simply wouldn't work, even though i had used a simalar technology on a piece last week. After hours of debugging, the only difference between the pflows was that in the working scene the stl check on all 1500 odd fragments used for the birth script said "no errors" and therefor this scene was flawless. Now the scene with the errors on the fragments reported "open edges" on the fragments. So, just as a heads up, I recommend that if you do fragmentation for birth scripts that you run an STL CHECK in max BEFORE you write the birth script. I don't quite know why birth scripts dislike open edges, but for the 5 hours of debug time, it certainly is worth checking, to save hours of hmmmmmmmmmm.

Topic  57  Initial State and PAraay.
Damn, is there any way i could make the initial state out of PArray object fragments? Im assumeing that initial state is restrained to pflow? ANy chance of this changeing in an upgrade? I doubt it will need to once fragmentation tools come. Can I make a script to tell init state to use a PArray?

Topic  55  Beta testing positions?
Their any possible way to apply for beta testing upcoming pflow box sets?

Topic  50  Birth scripts faster than birth events and position objects?
This really isn't a question, but more of an observation. It seems particle flow is faster at updating a scene when you use a birth script for geometry creation, rather than a birth event, a position object, a speed by surface, etc... Is this due to the fewer steps one has to calculate when the geometry is there, defined in a script.....

Topic  46  Particle Paint: No Spline, no nozzle cursor while dragging
I can't see the spline or the circle that should indicate the brush size while dragging a Freehand spline. Is it a setting that I'm missing? I'm working with max7, could this be the reason? Also, in max 7 the [6] shortcut doesn't work any more. I haven't changed the keyboard shortcuts. Any ideas? Andrea

Topic  41  Box 2?
When is Box 2 gonna be released? Im so hyped and I could seriosuly use it for my project that im doing over the next year and half for my portfolio when I graduate. Man, when PFlow can fragment geometry man.... talk about power in a can. It will be the ultimate particle solution.

Topic  39  two thumbs up for particle flow box#1
i have had particle flow box#1 for almost two weeks now and i think it is awesome. trying to do more r&d now it is winter here in Southern Ontario and hopefully will be uploading some examples shortly the coolest thing i discovered tonight is that you can use a lock/bond lock to object as a "counterbalance" to a force oparator For example set up a standard flow anywhere, a lock bond and a force, and a 10x10unit grid (or any size) in your scene point the emission of evento1 for a force with say force=0.5 turb=.5 scale=0.05 and freq =0.05 and also point to a lock/bond set to lock to object with a position strength set from 25-75% (shake well for best results) the lock/bond will act as an sine-wave damping factor to the force very very cool

Topic  34  render effects reading particle age of pflow
i know this is more of a maxscript concept but it does involve particles [u]event render and event #1[/u] lets say you set up just the default emitter with birth start=0 birth end=30 number of particles=200 view/render amount=100% you then use a send/out or agetest>particleage=0 to event #2 [u] event #2[/u] this event contains an agetest=30 and a delete by particle age=30 you wire the output to spawn delete parent (event 3) and wire the ouput back to the input of event #2 in effect creating a never ending loop of 200 particles now as every particles leaves event #3 (age =30) and comes back to event #2 (age=0) you can then set up a particle age material for these events particles flow and the material editor are totally aware of particle age, but if you set up a glow in the render effects with a particle age entered into one of the falloff or color slots contained in the setup of the glow it is not aware of the particle aging going on in the pflow event. it would be cool if there was a way of telling the render effects to adjust its glow parameters based on the particle age (or even other particle properties such as speed, scale, rotation relative to ther face normal, etc) if this was the case, you could have totally different render effects DEPENDANT upon what happens in particle flow... just a late night thought... mark raymond pigott avolution multimedia

Topic  29  PFlow updating...
Just something I have noticed...I have been working on some scenes using a fair amount of particles and when rendering them through Brazil; they seem to update over and over again. it gives the little readout in the bottom of the Max UI saying that the particles are updating and once it reaches 100% it goes through and updates them again. (seems to update 5 times for 5 events, 6 times for 6 events so on and so on...) Yet when using scanline it just renders through them with no updating needed...just wondering if you had any similar experiences with this issue. thanks
