Two additional controls in the mini-curve editor let you fine-tune the values of selected
points in the curve:
Spacing Over Stroke: A slider that adjusts the spacing between dabs at the selected
keyframe. Increasing this parameter increases the spacing between each dab in the
stroke.
Stroke Length: A slider that determines where along the range of the dabs within the
stroke the Spacing Over Stroke value (for the selected keyframe) is applied.
Fixed Brush Dabs: A checkbox that, when selected, keeps the number and spacing of
the dabs constant regardless of the changes in the stroke’s shape over time caused
by behaviors or keyframe animation. The effect of this parameter is not visible when
editing a paint stroke on a single frame.
Anchor Dabs To: A pop-up menu (available when the Fixed Brush Dabs checkbox is
deselected) that defines how dabs are added to or removed from a paint stroke when
the length of the paint stroke is modified. There are two options:
Start: Adds dabs to or removes dabs from the start point of a paint stroke when the
length of the paint stroke is modified. The first dab on the stroke remains fixed.
Start and End: Adds dabs to or removes dabs from the start and end points of a
paint stroke when the length of the paint stroke is modified. The first and last dabs
on the stroke remain fixed.
Note: Changing a shape’s control points or adjusting the Width or Spacing
parameters (in the Style pane) or Spacing Over Stroke and Width Over Stroke
parameters (in the Stroke pane) affects the dab spacing because larger dabs can be
spaced further apart.
Width Over Stroke: A mini-curve editor that lets you customize the width of the dabs
over the length of the stroke. You can create a curve that gradually increases the dabs’
width over the length of the stroke, create a curve that varies the dabs’ width over the
length of the stroke, and so on. The start value for the dab width is based on the value
set in the Width parameter in the Style pane. For more information on using the mini-
curve editor, see Use the mini-curve editor in Motion.
Two additional controls in the mini-curve editor let you fine-tune the values of selected
points in the curve:
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.
You can also adjust the Width Over Stroke parameter for a selected paint stroke in the
canvas. See Adjust stroke width in the Motion canvas.
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 affect only the
size of the dabs and don’t preserve the spacing between dabs.
