Hi everyone. Nice to see Quad has its own forums now!

Basically I'm working on an SP map, and I'm using quite a few custom textures. I'm currently adding specular and normal maps, but the weird thing is that these effects don't seem to show.

Well, they rendered once - and there was so much glare that the map was burned into my retinas for a week. I'd like to make these effects a bit more subtle, but the engine isn't applying these shaders any more. Thus progress is kind of on halt until I can see the changes.
Does anybody have any ideas as to what's going on? Pixel shaders seem to work with the default textures, so it's probably the way I've packaged it. The only thing is that it did work once. Then never again.

I've got a nvidia 9600gt gfx card, and all shader effects are enabled.
Map config and texture package files are attached.

Thanks.
