A scaling factor applied to particles' size. This lets you scale by different values in different axes to create oblong shapes.

This attribute is used for display and rendering, as well as by the Simulate Rigid Bodies node for determining collisions if CollisionScale is undefined.

If neither this attribute nor CollisionScale is defined, the default value used by the Simulate Rigid Bodies node is (1, 1, 1).

You can quickly get and set the Scale attribute using the Get Particle Scale and Set Particle Scale compounds.
