User Guide
When Displacement Detail values are set very high, the stroke may not resemble its
original shape at all. This is useful in creating randomly animated strokes.
Low Displacement Detail (left), Medium Displacement Detail (center), and High Displace-
ment Detail (right)
Set the Displacement Detail value by using the slider in the Effect Controls window (preset
to values between 0 and 100) or by clicking the underlined Displacement Detail value and
typing a number between 0 and 1000.
Selecting pressure settings
Note: Strokes that do not have either Stylus Radius or Stylus Opacity options selected are not
affected by the Wiggle Pressure Settings. However, these options can be enabled even when a
tablet is not installed.
To make the Radius and Opacity of mouse-drawn strokes wiggle, select those strokes in
the Composition window, and then select the Stylus Radius and Stylus Opacity options in
the Effect Controls window.
Checking the Stylus Radius and Stylus Opacity flags for strokes drawn with a pressure-
sensitive pen allows pressure information to be recorded. This information then
contributes to the variation of the stroke while wiggling is enabled.
Pressure Variation This value determines how much the Radius and Opacity values of the
stroke vary while wiggling. For strokes that have Stylus: Radius enabled, the Radius
wiggles. For strokes that have Stylus: Opacity enabled, the Opacity wiggles. The amount
of variation in either the Radius or Opacity value while wiggling depends on the value
specified for Pressure Variation.
