There are two categories of generators in the Library: Generators and Text Generators.
The Generator category includes static images, such as the Checkerboard generator, and
images animated by default, such as the Clouds generator. Although static generators
are not animated by default, you can keyframe their parameters to create an animated
pattern. All Text Generators are animated. You can use any generator as is or modify its
settings to create different effects.
Note: Generators contain Opacity and Blend Mode controls in the HUD. As with all objects
in Motion, the Opacity and Blend Mode parameters for any generator can also be modified
in the Properties Inspector.
Although the sliders in the Inspector are usually limited to a specific range, you can often
manually enter values outside of that range in the value sliders (the numeric fields to the
right of the sliders).
