Important: The Opacity parameter in the HUD is identical to the Opacity control located
in the Properties Inspector. This slider sets the transparency of the generator as a whole.
Several generators contain a separate opacity control in the Generator Inspector, which
is independent of the like-named control in the Properties Inspector.
Caustics
The Caustics generator creates an animated, simulated water surface. The size, speed,
refraction, brightness, and color of the Caustics pattern can be modified and animated.
You can use the Caustics generator to add light patterns to a project, or as the source
object for an image map.
Default Caustics generator Modified Caustics generator over an image
