This is a smaller pack today. Just several images of stuff I was messing around with for Chapter 40 of Bim U. I was trying to make Chris look like he had soot or dirt on his face. I think it turned out OK.
I also experimented with putting a hole in his shirt. I searched google for some images of burned holes, then I overlaid one of them onto the texture for his shirt and blurred them together. I had to manually draw a black and white version of that image to act as the opacity map to actually make a hole in his shirt. It turned out better than I had hoped! :D
