Shaders

Here is some general information about how they are used (for those who know how to write them).

More information can be found in the free shaders section of the wiki

By editing the shaders included with the engine you can get various effects, such as sepia, invert or cell shading effect. Shader files are located in the ProjectName/Shaders folder, and they can be changed via a script (see Scripting#shader, List of Commands, shader set). Only two object uniforms are passed to the shader - the texture and the number of activated light sources. The sources themselves are sorted by the engine in descending order, and the shader uses OpenGL's built-in variables to access the sources.
