Scale Chaos group
These options apply random scaling to the
particles.
Factor—Determines a random percentage range of
scaling of the spaw ned particles relative to their
parents, and dependent on the options below.
Down—Randomly scales down spawned particles
to b e smaller than their parents, based on the
Factor value.
Up—Randomly scales up spawned particles to be
larger than their parents.
Both—Sca le s spawned particles both larger and
smaller than their parents.
Use Fixed Value—Uses the Factor value as a fixed
value, rather than a r ange of values.
Lifespan Value Queue group
These options let you specify a list of alternative
lifespan values for each spawned generation
of par ticles. The spawned part icles use these
lifespans rather than the lifespan specified for the
original part icles in t he Life spinner on the
Particle
Generation rollout (page 2–256)
.
List window—Displaysalistoflifespanvalues.The
first value on the list is used for the first generation
of spawned particles, the next value is used for
the next generation, and so on. If there are fewer
values on the list than there are spawn ings, then
the last value is used repeatedly for all remaining
spaw nings.

list window.

instanced-object particles with each spawning (as
set with the Spawns spinner). These options are
available only if Instanced Geometry is the current
part icle t ype.
List window—Displays a list of objects to be
instanced as particles. The first object on the list
is used for the first spawning, the second for the
