• Add and Subtract: Values generated by this behavior are added to and subtracted from
other behaviors and keyframes that affect the same parameter.
Frequency: A slider that lets you adjust the amount of random variation per second.
Higher values generate faster variations, whereas lower values generate slower variations.
Noisiness: A slider that adds an additional overlay of random variance to the Frequency
you’ve set. Higher Noisiness values result in more erratic variations in the affected
parameter.
Link: This parameter appears when you apply this behavior to a two-dimensional
parameter (such as Shear) or three-dimensional parameter (such as Position or Rotation)
that consists of X, Y, and/or Z values. Turn this checkbox on to keep the behavior’s effect
on each value proportional.
Preserve Angle: When this checkbox is selected, the tangent handles become (or remain)
flat, maintaining the continuity of the curves.
Random Seed: A button that lets you pick a new random seed number. This number is
used to randomly generate new sequences of values, based on the other parameters of
this behavior.
HUD Controls
The Randomize Shape HUD contains the Amount, Multiplier, Apply To, Frequency,
Noisiness, Link, and Preserve Angle parameters.
Sequence Paint
The Sequence Paint behavior allows you to animate the individual dabs of a paint stroke
in sequence over time. This is the only way to animate the dabs individually—keyframing
the stroke parameters or applying other behaviors affects all dabs in the stroke uniformly.
