Apple Motion 4 - Manual (Page 1142)

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.
For an example of using a sequence behavior, see Using the Sequence Replicator Behavior .
Parameters in the Inspector
Sequence Paint: A checkbox that turns sequencing on or off. Before any sequencing
animation can occur, you must explicitly add at least one parameter to the behavior from
within the Inspector, and then set a value for that parameter. Until a parameter is added,
adjustments in the Inspector or HUD have no effect.
Parameter: Use the Add and Remove Parameter pop-up menus to add and remove
parameters to the sequence. Once the parameter is added, additional controls appear in
the Behaviors tab of the Inspector. Adjust those controls to create a sequence animation
based on the difference between the original value of the dabs and the modified value.
There are six menu options and related controls:
• Rotation: Specifies (in degrees) the rotation of the stroke dabs. You can either rotate
the dial or use the value slider. Click the disclosure triangle next to the Rotation
parameter to reveal separate X, Y and Z Rotation controls.
• Color: Specifies a color to use to tint the stroke dabs. You can either click the color well
to choose a color, or open the disclosure triangle and use the Red, Green, and Blue
sliders or value fields.
• Opacity: Defines the opacity of the stroke dabs. Set a new value using the slider.
• Scale: Defines the scale of the stroke dabs. Click the disclosure triangle next to the Scale
parameter to reveal separate X Scaling and Y Scaling subparameters, which can be
used to scale the width and height of the dabs separately. By default, Scale is set to
100%—the size of the stroke dabs is equal to the original size defined in the stroke
parameters.
• Width: Defines the width of the dabs. Unlike Scale, Width adjustments will alter the
size of the dab while also maintaining the spacing between each dab. Set a new value
using the slider.
