Sepia Shader

From C4 Engine Wiki

Convert a color output to sepia tone

A simple extension to the Grayscale Shader.

To use this shader is really simple. Just copy it into BOTH the ambient and light tabs of the shader editor. Then, wherever you see a route leading to an rgb input of an output process, reroute it so instead of going to an output process it goes to the shader first. After that, create a route from the shader to the output process where the original route was headed. Remember to this in both tabs of the editor.

Works with normal mapping, parallax mapping, horizon mapping, specular, reflection, and refraction
