CausticMapComp Simulates the patterns created when light rays are reflected or refracted by a curved surface. Caustics can often be seen at the bottom of a swimming pool in bright sunlight or on objects viewed underwater. Inputs: Map: The clip to use as height map. Back: The clip to use as background.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Softens the caustic pattern.

Blur Map: Default: 0.2, Range: 0 or greater.
The blur applied to the height map

Brightness1: Default: 0.5, Range: 0 or greater.
Scales the brightness of Color1. Increase for more contrast.

The color of the 'brighter' parts of the texture. The colors of the result are determined by an interpolation between Color0 and Color1.

Color0: Default rgb: [0 0.05 1], Shared .

Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.
