I am not sure if I just don't get how to use shaders, but I am not sure how to use this.

I have:
1. included nm.wdl in my main script
2. imported a mdl with diffuse map in skn1 and normal in skn2
3. build and I get my model, no effects on it though.

Am I doing something wrong here? what is nm_mat that is mentioned? Is that what my material has to be named? If so, how would I have more than 1 material if they are all named that?

thanks in advance.
