Animating Generators

Although most generators create static images, you can animate the parameters of a
generator to create a moving texture over time. This section discusses using the Generator
Inspector to animate the Checkerboard generator from the above example.

Note: You can also animate the parameters of an animated generator.

For information on using Parameter behaviors to animate a generator, see


Behaviors to Generators


To animate Checkerboard generator parameters


Move the playhead to the frame where you want to begin the animation.


Press A to turn on keyframe animation recording.


With the generator selected, set the initial parameter values in the Generator Inspector:


Drag the Size slider to set the initial checker size.


Click the color wells and pick the initial colors.


Drag the Contrast slider to set the initial contrast value.


Drag a Center parameter value slider to set the initial Center value.

The value slider on the left of the Center parameter controls the X position of the
checkers, and the value slider on the right controls the Y position. To animate checkers
horizontally, use the left value slider. To animate checkers vertically, use the right slider.
