•
Width Over Stroke: A slider that adjusts the width of the dab at the selected keyframe.
•
Stroke Length: A slider that determines where along the range of the dabs within the stroke
the Width Over Stroke value (for the selected keyframe) is applied.
The Width Over Stroke parameter can be adjusted on the selected paint stroke in the Canvas.
For more information, see Use the Width Over Stroke onscreen controls on page 866.
•
Brush Scale: A slider that adjusts the size of the brush (the source of the dabs). Click the
disclosure triangle to adjust the X and Y scale values independently. By default, Scale is set
to 100%—the size of the dabs is equal to the size of the source brush. Unlike the width
parameter in the Style pane, brush scale adjustments aect only the size of the dabs and don’t
preserve the spacing between dabs.
•
Brush Scale Randomness: A slider that denes an amount of variance in the scale of the stroke’s
brush. A value of 0 results in no variance—all dabs in the stroke are the same size. A value
greater than 0 introduces a variance. The scale for an individual dab is dened by the Scale
parameter, plus or minus a random value falling within the Brush Scale, Width Over Stroke,
and Width (in the Style pane) parameters. Click the disclosure triangle to adjust the X and Y
values independently.
•
Align Brush Angle: A checkbox that, when selected, causes the stroke dabs rotate to match the
shape on which they are positioned.
•
Brush Angle: A dial that species (in degrees) the rotation of the stroke dabs. Using the default
dial or value slider modies the Z angle. When the Local 3D checkbox is selected, additional
Brush Angle Randomness controls become available. Click the disclosure triangle to expose X,
Y, and Z rotation dials and the Animate pop-up menu.
•
Animate: A pop-up menu, available when the Local 3D checkbox is selected, that lets you
change the interpolation for animated 3D rotation channels. Click the Brush Angle disclosure
triangle to display the Animate parameter. By default, Animate is set to Use Rotation.
•
Use Rotation: Dabs rotate from their start rotation to their nal rotation. Depending on the
animation, the elements may rotate multiple times before reaching their nal orientation
(the last keyframed value). For example, if the X, Y, and Z angle parameters are animated
from 0 degrees to 180 degrees in a project, the elements rotate on all axes before reaching
their nal orientation.
•
Use Orientation: Dabs rotate more smoothly and without multiple rotations. This option
interpolates between the dabs’ start orientation (rst keyframe) and their end orientation
(second keyframe).
•
Angle Over Stroke: A mini-curve editor that lets you customize the Z rotation (in degrees) of the
dabs over the length of the stroke. You can create a curve that gradually increases the dabs’
angle over the length of the stroke, a curve that varies the dabs’ angle over the length of the
stroke, and so on. Select or add a keyframe in the graph to make changes using the Angle
Over Stroke and Stroke Length controls, available under the graph:
