Size group
Scale Factor The amount of uniform scaling to apply to each spawned particle,
as a percentage of its parent's size. Default=100.0.
Variation The amount by which a spawned particle's scale can vary randomly.
Default=0.0.
To obtain the actual scaling for each spawned particle, the system multiplies
the Variation value by a random number between -1.0 and 1.0, and then adds
the result to the Scale Factor value. For example, if Scale Factor=100 and
Variation=20, then each spawned particle would be between 80 and 120
percent of its parent's size.
Uniqueness group
The Uniqueness setting enables randomization of the Spawnable result, when
less than 100.0, as well as of the Variation values.
Seed Specifies a randomization value.
New Calculates a new seed using a randomization formula.
Speed Test
Particle View on page 2811 > Click Speed Test in an event or add Speed Test to
the particle system and then select it.
Speed Test lets the particle system check particle speed, acceleration, or the
rate of circular travel, and branch accordingly. The test provides a number of
variants that let you test speed or acceleration on specific axes, or simply
whether the particle is accelerating or decelerating.
