Remap Color

Lets you remap a three-channel input (such as RGB color) to another three-channel output with three gradient controls for more precise shading.

You can also use this utility for non-shading purposes, however. For example, you could connect the translate of one object to remapColor.color, then connect remapColor.outColor to the translate of a second object, which effectively maps the position of one object onto the other. In this particular case, the second object initially follows the first then stops outside a zero to 1 bounding box. (To increase the size of this bounding range, increase both the input and output Min/Max settings.) If you reverse the gradients, the second object moves in the opposite direction. And if the graphs are wiggly, the motion of the second object would also be wiggly.

Render Pass Mode

Use this attribute in conjunction with your multi-render passes workflow.

Passthrough: Shader does not affect render passes.
Apply to Render Passes: Perform the same operation on material render passes as is performed on the master beauty pass.
No Contribution: Shader does not contribute to render passes and blanks out contributions made by upstream shaders.
Write Shader Result to Beauty Passes: The color computed for the master beauty pass is propagated to all other beauty passes.
