With 2.4 supporting HDRI, Reflections, Animated textures, Terrain Blending, Specular lighting, Texture transformations, Bloom, Alpha channels and other stuff, It is getting hard to keep track of all these shader functions. The "shader bible" is not specific to darkplaces and you never know what will and will not work. Could somebody please post a darkplaces specific shader reference, a list of new functions or at least some more example shaders in the "shaders" thread.
I posted a question there which nobody seems to have the answer for: What is the shader equivalent of having a _bump, _gloss, and _glow with your texture?
