Collision

Sets attributes on and/or groups particles when they collide with geometry.

See also: Emitter, Source from Geometry, Limit, Soft Limit

The default setting is bounce on collision, which causes particles to bounce off the surface of an object. However, the behavior can be modified in the operation controls toolbar or in the parameter editor to: die, stop, stick, or slide on collision. You can also set the behavior to continue on course, which makes the particles pass through the object. This tool is useful for defining how particles should react when they collide with objects.

Using Collision

  1. Select the particle system you want to be affected.

  2. Click the Collision tool on the Drive Particles tab.

  3. Select the object you want the particles to affect and press Enter to confirm your selection.

    Choose how the particles will react in the Behavior drop-down menu on the operation controls toolbar or in the parameter editor.
