Sorry! I can't provide a quick and comprehensible guide. However, I will attempt to explain the inner most workings of Evolved's Multi-Pass Lighting & Normal Mapping Shader. Well, maybe just how to find clues in the shader code and how to use that in DBPro. OK, lets open the shader file and see what it needs to do its magic.

Sorry, have to logoff for now.

In the next installment we will go over the shader file in sections and discover what functions it provides and how to use them in DBPro.

Stay tuned!
