I would like to incorporate some GLSL into a project I am doing with Blender - mainly fresnel water with animated noise bumpmapping. I’m not worried about the actual GLSL shaders, that I can do - at least I can code it if I can figure out the relevant maths. My question is: How do you attach the shaders to an object or material so that the GE knows to use them? I can’t figure it out from the examples.
Also, on an unrelated (or possibly related) topic, how does one make faces transparent and keep them that way in the GE? It might be my PC but it seems that varying material alpha values does one of two things. Alpha > 0.5, no transparency. Alpha < 0.5 face is invisible. This happens with Blender materials on or off. Anyone got any ideas?
