Corona Tonemap Control Shader

This article explains the settings and values for the Corona Tonemap Control shader.

Overview

The Corona Tonemap Control shader transforms the texture using the inverse of the current color mapping, effectively removing any postprocessing color mapping from it. This can be useful for displaying an emission / self-illumination texture that exactly matches the input bitmap in the resulting render under any color mapping. For this feature to work correctly, the color mapping cannot be changed after the render is started.
