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.
Adjust this generator using the controls in the Generator Inspector:
Size: A slider that sets the size of the shapes and spaces in the pattern.
Speed: A slider that sets the speed of movement of the light patterns.
Refraction: A slider that sets the refraction of the light shapes.
Brightness: A slider that sets the brightness of the light shapes.
Color: Color controls that set the color of the light shapes. For more precise color selection, click the disclosure triangle to display Red, Green, and Blue sliders.
