Common Environment texture attributes
Color Remap applies a color map to the texture. It is the only common Effects Environment texture attribute. The U value of the Color Remap texture is mapped to the original texture’s hue, and the V value is mapped to the original texture’s intensity (the value defined by [R+G+B]/3). The Color Remap attribute acts similar to the Shading Map material (see Shading Map).
