Apple Motion 4 - Manual (Page 1083)

Using the Write On parameter, you can record a stroke so that it “draws” over time. In
this case, a Write On Shape behavior is applied to the stroke using as its settings the time
it took to draw the stroke and the speed at which each section of the stroke was created.
These settings can be modified after the stroke is created. A Write On behavior can also
be applied after a paint stroke has been created. For more information on using the Write
On behavior, see
Write On .
To make a paint stroke
1 Select the Paint Stroke tool (or press P).
Paint Stroke tool
The Paint Stroke tool HUD appears. (If it doesn’t appear, press F7.)
Important: Like the other drawing tool HUDs, the Paint Stroke Tool HUD is available only
after the Paint Stroke tool is selected and before you create your stroke in the Canvas.
The Paint Stroke Tool HUD allows you to determine the properties derived from the
pressure and speed of the stylus before the stroke is drawn.
2 Define a paint stroke style in the HUD:
a Choose an option from the Shape Style preset pop-up menu.
b Modify the Brush Color and Width settings.
If a preset is not used, a basic solid stroke is created. Once the stroke is created, you
can still apply a preset to the stroke using the Inspector. Presets do not override the
width or color of the stroke set in the HUD.
Note: The Pen Pressure and Pen Speed parameters become available depending upon
the chosen style. These parameters are not available with a solid brush type.
3 If you want to create a stroke that is drawn over time, select the Write On checkbox.
