Hi just would like to present some interesting shaders that would be possible in GE.
D-Man create some very nice shaders look this thread.

Since for BSOC we have a coder creating Blender materials to work in real time via GLSL, I wonder if such code could be ported over to game engine, so we wouldn’t need to code special shaders and whatnot…
