Uniqueness group
The Uniqueness setting affects the randomization of orientation with the
Random 3D and Random Horizontal options, and also Divergence.
Seed Specifies a randomization value.
New Calculates a new seed using a randomization formula.
Spin Operator
Particle View on page 2811 > Click a Spin operator in an event or add a Spin
operator to the particle system and then select it.
The Spin operator gives an angular velocity to particles in an event, with
optional random variation. Spin is applied once per event per particle, except
when using the Speed Space Follow option; however, the settings can be
animated.
To simply specify particle orientation, use the Rotation operator on page 2861.
Interface
The user interface appears in the parameters panel, on the right side of the
Particle View dialog.
Spin Rate The rate of revolution in degrees per second.
