Apply Mode: A pop-up menu that determines how values generated by this behavior
are combined with other behaviors and keyframes that affect the same parameter. This
provides you with different ways of using a Randomize behavior to modify a vertex’s
preexisting values. The options are Add, Subtract, Multiply, or Add and Subtract.
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
(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.
Sequence Paint
Sequence Paint 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.
The Sequence Paint behavior is very similar to the Sequence Text and Sequence
Replicator behaviors, which allow you to animate the Rotation, Color, Opacity, Scale,
and Position parameters in sequence through the characters of a text layer or the
elements of a replicator pattern. The Sequence Paint behavior adds Width to that list of
parameters, allowing you to create sequenced animation through the dabs of a paint
stroke.
