Ashley , what is been asked is for a unified "lighting" system that takes into account any light(s) position, color, intensity withing the layout, and reacts accordingly to both:
a) Illuminating the scene (casting shadows, preferably with a falloff option)
b) Responding to any normal maps.
The lighting-shadowing system that exists in c2 now is problematic, having more than one light sources produces artifacts, it needs a lot of preperation just to achieve a simple falloff effect and it doesn't react at all with normal textures.
The normal-bump effect within c2 is not useful for most situations.
I hope the above make sense, I can't express my self more clearly that this, I'm sorry, we are hitting the language barrier here
