Feasible DFA concept idea

Feasible Environment Idea

The environment in which I am doing in DFA demands a complex material making when brought into UDK. The idea is that wherever the light hits, a clean looking material will be applied. However, where the lights don't hit, a grunge and dirty material will be applied. 

Drawing it in 2d form will be quite easy. However, material making for UDK will cost time and effort. 

HOWEVER! I've got it semi-working at the moment.

The picture represent how the lit area shows one material and unlit area shows another material. I've just used UDK textures, but that's only to start the experiment with.

I'll need to fine tune the material so that I can create a master material for the environment that I will most likely be working on in DFA.
