Using Shapes and Masks
Unit Size: Specifies whether the sequence animation is applied to the stroke as a
whole, to its individual dabs, or to a keyframed range. The Unit Size options are:
 Dab: Applies the sequence animation over each dab as its own entity. Dab is the
default setting.
 All: Applies the sequence animation to all stroke dabs simultaneously.
 Custom: Allows you to specify the percentage of dabs on the stroke that are
affected by the sequence animation at once. Although you can create keyframes for
the Custom option, it is not required in order to affect the sequence. Custom allows
you to define an area of dabs—based on percentage—that are affected by the
sequence.
 Start: Available when Unit Size is set to Custom, this parameter allows you to
specify the starting point for the dabs on the stroke (based on percentage) that is
affected by the animation.
 End: Available when Unit Size is set to Custom, this parameter allows you to
specify the ending point for the dabs on the stroke (based on percentage) that is
affected by the animation.
Spread: To create a softer transition between dabs, increase the Spread value. (This
parameter is not available when Unit Size is set to All.)
Traversal: A pop-up menu that sets the action of the sequence behavior to Constant
Speed, Ease In, Ease Out, Ease In/Out, Accelerate, Decelerate, or Custom.
 Constant Speed: Moves the animation from the origin of the paint stroke through
the end of the stroke at a constant speed. The sequence moves in the direction in
which the stroke was created.
 Ease In: The sequence animation begins slowly and increases to normal speed as it
moves through the paint stroke.
 Ease Out: The sequence animation begins at normal speed and slows toward the
end of the paint stroke.
 Ease In/Out: The sequence animation begins slowly, increases to normal speed as it
moves toward the middle of the stroke, and slows as it reaches the end of the paint
stroke.
 Accelerate: The sequence animation increases in speed.
 Decelerate: The sequence animation decreases in speed.
 Custom: Allows you to keyframe how the animation moves through the paint
stroke. When you choose Custom from the Traversal pop-up menu, the Location
parameter replaces the Loops parameter.
 Location: Defines the location of the stroke where the animation is in effect.
