Matt_Aufderheide,
I am trying to use your shader converted to ps_2, but it gives me the following error message:
Error in effect:
your_world_texture_normalmap_tga(187):error X4502: invalida output semantic 'TEXCOORD9'(416): ID3DXEffectCompile::CompileEffect: There was an error compliling expresion ID3DXEffect

compiler: Compilation failed.

Can you help me?
