Direction Chaos group
Chaos Specifies the amount by which the direction of the spawned particle
can vary from the direction of the parent particle. A setting of 0 means no
variance. A setting of 100 causes the spawned particle to travel in any random
direction. A setting of 50 causes the spawned particle to deviate from its
parent's path by up to 90 degrees.
Speed Chaos group
These options let you vary the spawned particles' speed randomly in relation
to their parents' speed.
Factor This is the range of a percentage of change in the speed of the spawned
particle relative to its parent. A value of 0 means no change.
Slow Applies the speed factor randomly to slow the speed of the spawned
particles.
Fast Randomly speeds up particles based on the speed factor.
Both Some particles speed up, while others slow down, based on the speed
factor.
Inherit Parent Velocity Spawned particles inherit the speed of their parents,
in addition to the effect of the speed factor.
Use Fixed Value Uses the Factor value as a set value, rather than as a range
applied randomly to each particle.
