Use the Size Operator to assign any size to a selected
particle input data stream. Keep in mind that this operator is valid as
long as the ON input data stream is set to true, and that by default,
the size values applied are immediate, and not gradual over time.
ON - (Bool) This input data
stream determines whether the operator is considered 'on' or 'off'. You
can connect other operators to this input channel such as a Bool
Helper to activate/deactivate the whole operator.
Time - (Time) This input data stream is used to define the local
time for the operator when the user wants to override the default system
time.
Particle - (Particle) This input data stream reads in the currently
selected particle group that is to have its size adjusted. The data stream
MUST be connected and will be highlighted yellow if it
is not.
Size - (Size) This input data stream is used to override the Size
spinner in the Size rollout.
Size Variation - (Scalar) This input data stream is used to override
the Variation % spinner in the Size rollout.
No Operator Outputs.
Size - Use the Size spinner to set a specific particle size in
3ds Max World units.
Variation % - In order to avoid having all particles with the
exact same size, increase the Variation percentage value to create more
randomization in the sizes between particles.
