Collision

Overview

Configure particle collision settings. When collision is enabled, particles can react to the specified plane or external collision shapes with effects such as bounce and slowdown.

Parameters

enable

Enables collision.

Collide With Ground

Enables collision against the ground shown in the Environment panel.

External Collision

Enables collision against externally provided collision shapes.

Bounce

Sets how strongly particles bounce on collision.

Friction

Sets how much particles slow down on collision.

Height

Sets the height of the collision plane.

Lifetime Reduction

Specifies how much lifetime is reduced when a collision occurs.

Coordinate System

Sets the coordinate system used for the collision plane height (local/world).
