The Control class of components is used to introduce randomness to otherwise regular texture parameters. Most texture components in the Gradient and Pattern classes and a few Natural textures generate regular patterns with distinct regions. Control components have the ability to randomize any color, value, or transform for these textures. For example, you could make every stone in the Flagstone component a different color.
Control components are modifiers, and so must be linked to other components to be useful. To use one, link regional-type parameters of other components to the Control component.
