To obtain the actual speed 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 particle's speed as specified or inherited. For example, if a
particle's speed is 100 units/second and Variation=20, then the tested value
for each particle would be between 80 and 120 units/second.
Divergence When on, spreads out the stream of spawned particles. Use the
numeric setting to define the extent of the divergence in degrees. Range=0 to
180. Default=0.
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.
Find Target Test
Particle View on page 2811 > Click Find Target in an event or add Find Target
to the particle system and then select it.
Select a Find Target icon in the viewport. > Modify panel > Parameters rollout

By default, Find Target sends particles to a specified target or targets. Upon
reaching a target, the particles become eligible for redirection to another event.
You can specify that the particles should use a particular speed or time frame
