Apple Motion 4 - Manual (Page 1084)

When a paint stroke is created with the Write On checkbox selected, a Write On behavior
is applied to the stroke. Like any other behavior, you can modify its parameters in the
HUD or Inspector. For more information on using the Write On behavior, see
Write On .
4 Draw your stroke in the Canvas. Once the stroke is complete, press S or Esc to select the
Select/Transform tool.
The Paint Stroke Tool HUD is replaced with the Shape HUD. The Paint Stroke HUD
parameters are identical to all other shape HUDs. Once a stroke is drawn, you must use
the Inspector to modify parameters unique to the paint stroke and its dabs.
The lower portion of the Paint Stroke Tool HUD contains a sketch area and a play button.
This allows you view a preview of what a paint stroke effect will look like.
To preview the paint stroke in the Paint Stroke Tool HUD’s sketch area
1 Click the Paint Stroke tool in the Toolbar.
2 Do one of the following:
• Select any brush style in the Paint Stroke Tool HUD, then draw a stroke in the sketch
area to see a preview of the paint stroke.
• Select the Write On checkbox, draw a stroke in the sketch area, then click the Play
button to see a preview of the write-on stroke.
• Apply a preset from the Shape Style pop-up menu to an existing stroke in the sketch
area.
If the preset is an animated stroke, the stroke is automatically drawn in the sketch area.
Press the Play button to see the stroke animation again.
Note: To create a paint stroke that is “painted” on the Canvas over time (if your chosen
preset is not animated), select the Write On checkbox in the HUD prior to drawing the
paint stroke in the Canvas.
Important: Some operations, as well as the application of certain filters or a mask, cause
a group to be rasterized. Because all paint strokes live in groups, this affects how strokes
interact with other objects within your project. For more information, see
Groups and
Rasterization .
Paint Stroke Tool HUD Parameters
The Paint Stroke Tool HUD is displayed after the Paint Stroke tool is selected in the Toolbar
and before a stroke is drawn. This HUD contains controls that define the color and width
of the stroke and how pen pressure and speed affect the stroke (opacity, width, and so
on), a checkbox that allows the stroke to be “drawn in” over time, smoothing controls,
and a Shape Style pop-up menu for quick access to preset brush styles and a sketch area
for sampling these brush styles.
Brush Color: A color well and eyedropper that set the color of the brush. For more
information on using these controls, see Color Controls .
