Scale setting in the Shape operator on page 2900, or a Shape Instance operator
on page 2904.
For instance, if you previously used Scale with Overwrite Once to scale particles'
birth size within a range, and then want to scale them to half their previous
size, use Inherit Once and set Scale Factor to 50%.
Absolute Sets the scale continuously, while the particle is in the event, as an
absolute percentage value, disregarding any previous scaling.
Use Absolute if you want to animate the particles' scale explicitly.
Relative First Sets the scale continuously, while the particle is in the event, as
a percentage of existing scaling. The existing scaling should be specified with
a previous Scale operator, or a Shape Instance.
Use Relative First when you want to scale the particles relative to the scaling
at which they enter the event, and optionally animate the scaling, or before
a Relative Successive operator.
Relative Successive Scales the particles continuously, relative to scaling set
earlier in the same event.
NOTE Always precede Relative Successive in the same event with an operator that
modifies the scale channel all the time, such as a Scale operator set to Absolute
or Relative First, or a Shape Instance operator with the Scale check box turned on
(it's on by default).
Scale Factor group
The operator performs scaling on each particle's local axes. It can scale particles
on a single axis or on any combination of axes.
X/Y/Z Sets the scaling as a percentage of the particle's current size. To scale
uniformly, turn on Constrain Proportions, and then change any axis setting.
Range=0 to 10000000. Default=100.
Constrain Proportions When on, retains the current ratio of scale factor
settings, so that changing any axis setting changes all of them. Default=on.
Scale Variation group
X/Y/Z Sets the scaling variation as a percentage of the particle's previous size.
To scale uniformly, turn on Constrain Proportions, and then change any axis
setting. Range=0 to 100. Default=0.
Constrain Proportions When on, retains the current ratio of scale variation
settings, so that changing any axis setting changes all of them. Default=on.
