So I've gotten a couple of questions regarding the materials that I used for this project.
The materials are very, very standard as UDK goes. Screen cap below.
Most every object uses this set up with exception for the glass eyes, sky and other odds and ends.
As far as the ink on the object silhouettes I'm using the sobel edge detector posted on the UDN website.
Most of the look and feel is obtained through texturing and lighting.
If anyone else has any questions please ask in the comments!
