I kinda got that drift Arcturus... Yes a good point of reference @Biker: Yes, you need to fix your Ambient_World issue, that Doom 3 default ambient (Normal) is UUUUUGLY! Just look at how it ruins the shading on your wood textures. Blargh! Honestly, they should have replaced the "Normal" ambient with Rebb's shader but I understand it's good for trouble-shooting purposes (etc).
