Bounce

The Bounce model is used to make particles bounce off of layers in the composition.

Up to three layers can be assigned as Bounce Layers. NOTE: Animations for the layers are not registered, only the starting location for the layer.

Turn on Enable Bounce to activate the Bounce Simulation.

Bounce Layer

Use the Layer picker within the Bounce groups to select the layer to be used as the bounce surface. Layers need to be 3D-enabled with the 3D layer switch, and should have the 'Continuous Rasterize' switch turned off.

Bounce Mode

Use Bounce Mode to select how the layer will be seen:

• Infinite Plane : extends the size of the layer to create an infinite plane
• Layer Size : the size of the layer will be the edges of the bounce, and the particles can fall off the sides.
• Layer Alpha : utilize any layer within that layer to get the shape you want.

Collision Event

Controls what happens during a collision. Either Bounce , Slide , Stick or Kill . The kill mode is useful when the Aux Emitter is set to emit at collision and it is desired to remove the main particle at collision.

Bounce Strength

Bounce determines how much energy is conserved during the Bounce. High values make the particles bounce high.

Bounce Random

Randomness for the Bounce value. High values apply more randomness to the Bounce. Bounce Random makes the particles bounce a little differently in height, which makes the composition look more realistic.

Slide Friction

Used in conjunction with Gravity, control the friction of the material that is being bounced against. High values mean the particles will get stalled quickly. Low values mean they will slide around a lot, as if on an ice surface.
