Also, I've been working on my Post Apocalyptic environment, I didn't do any drastic changes with the composition but I am working on adding vehicles, extra buildings and small details to make the scene feel more "alive".
All colors can be tweaked with just one texture e.g. with a greyscale concrete texture I can create a red/green/blue one with the same shadersetup.
I might do a scene based on this shader study also all feedback is welcome!

Metal Shader Overview [WORK IN PROGRESS]
These are not the final settings of the metal mastershader but for testing the bounce light in UDK it was pretty handy. On assets within an environment, fine tuning the shaders would be easier in my opinion.
