public var pivot: Vector3;
public Vector3 pivot;

Description

Modify the pivot point used for rotating particles.

The units are expressed as a multiplier of the particle sizes, relative to their diameters. For example, a value of 0.5 would adjust the pivot by the particle radius, allowing particles to rotate around their edges.
