Colliders

Colliders act as objects particles can collide with and consist of connected line segments. Add colliders using the object list or alternatively, by holding CTRL and left-clicking on the effect preview. You can then set the collider's vertices with additional clicks. The following properties can be adjusted in the property panel to influence the behavior of a collider.
