988 Chapter 11 Working with Generators
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.
3 In the Library, navigate to the Generators category.
Note: You can also save the modified generator in another category, such as Favorites.
