PhysX Shape Operator

Restitution - The amount of energy each particle retains after a collision. Typically this produces a bouncing effect. Setting this to 1.0, the maximum value, potentially results in a condition that satisfies Newton's third law: To every action there is an equal and opposite reaction.

When Restitution is close to 1.0, the bounce effect is pronounced, but as a result, not much energy is dissipated during a collision, and the dynamics solution might lack stability. Use values close to 1.0 at your own risk: when you have a small number of colliding objects, and they don't bundle together.

Note: These settings of Bounce and Friction group determine how particles interact with other elements in the simulation (other particles, deflectors, the ground), so are meaningless in isolation. To determine the actual value for an interaction, the software takes the average of the properties of the interacting elements.
