I just want to say thank you on behalf of all of us for this shader work! I worked out my normal map tesselation problem and I'm now using flat color textures with detailed normal maps and the results are truly awesome! With a little attenuation and gloss tweaking, I can get great bump and specular effects! Here's a shot of how it stands now, very doom-like in appearance!
I think I'll stick with this formula if it checks out OK on my other PC's (mixture of hardware).
