The Bounce effect lets you to make particles bounce off a surface with realistic physical modelling. This node should have a region connected to it, and that region will act as a bounce plane so when any particle hits it, it will bounce off at the correct angle.

Bounce Properties

Parameter Description
Name Lets you rename the node.

An on/off switch using binary code. 1 = on, 0 = off.

Friction Enter a value in this field to increase the amount of friction each particle experiences as it makes contact with the planar surface. A positive value creates more friction and slows the particle down. A negative value lessens the friction and makes the surface appear more slippery.
Resilience Increases or decreases the bounciness of the particle. A value of zero causes the particle to hit the planar surface once and slide off any downward facing angle. A positive value, even by decimal increments, causes the particle to become bouncy. A negative value deadens the effect, the same way a lack of Region would.
Cutoff Speed Increasing this value widens the bounce arc. If the connected Planar Region is completely flat, a value of zero will cause the particle to bounce up and down in place. A tilted plane in the direction of the bounce will also widen the arc.
