I haven't used C-Script since 2007, I think.

It could be that the shader is working, but not getting any lights. Look up the "sun_light" variable in the manual.

Another option is to work through the shader workshop. Once you've done the first 4 workshops (won't take long) you'll not only have your own normal mapping shader, but enough understanding to modify it to your needs.

Have you used other shaders before? Do examples in the GStudio7 folder that use shaders work?
