number between -1.0 and 1.0, a nd then adds the
result to the Test Value setting. For example, if Test
Va lue=10 and Variation=5, then the tested value
for each particle would be between 5 and 15.

Test Value—The specific scaling fac tor to test for.
Default=100%.
Variation—Theamountbywhichthevaluetested
for can vary randomly. Default=0.0%.
To obtain the actual test value for each particle, the
system multiplies t he Variation value by a random
number between -1.0 and 1.0, a nd then adds the
result to the Test Value setting. For example, if Test
Value=100% and Variation=10%, then the tested
value for each particle would be b etween 90% and
110%.

•
Absolute T ime—Any keys set for p ar ameters are
applied at the actual frames for which they’re
set.
•
Particle Age—Any keys set for par ameters are
applied at the corresponding frames of each
particle’s existence.
•
Event Dura tion—Any keys set for parameters
are applied to each particle starting when it first
enters the event.

Script Test lets you test particle conditions using a
MAXScript script. The scr ipt can use any program
functionality available to MAXScript.
The default test script tests for the presence of all
particles within a spherical volume of radius 20.
