3 Set the initial generator parameter values:
• Drag the Size slider to set the initial checker size.
Once a keyframe is set for any parameter in a generator, a keyframe is set for all of
the generator parameters. In other words, once the Size parameter is keyframed, the
Color 1, Color 2, Contrast, and Center parameters are keyframed.
• Click the color wells and pick the initial colors.
• Drag the Contrast slider to set the initial contrast value.
• Drag one of the Center parameter value sliders to set the initial Center value.
The value slider on the left of the Center parameter is the X position of the checkers,
and the value slider on the right is the Y position. To animate the checkers
horizontally, use the left value slider. To animate the checkers vertically, use the right
slider. To view the X and Y parameters, click the Center disclosure triangle.
4 Go to the frame where you want to create the next keyframe.
5 Change the generator Size, Colors, and Contrast parameter values.
6 Play the project (press the Space bar).
The animated generator parameters create a moving, changing texture.
Saving Modified Generators
Once you have modified the parameters of a generator, you can save the generator to
the Library. For organizational purposes, it is recommended that you name objects that
you save back to the Library with a descriptive name. For example, if you save a
Checkerboard generator, it is named “Checkerboard 1” by default.
To save a customized generator to the Library:
1 To rename the modified generator, double-click the generator name in the Layers tab.
2 Type the new generator name, then press Return.
