I made a cluster for the head polygon so that I can make a separate UV map for it. I used a 2500 pixel for the head and 2500 for the body
For the texture, I always like green orc; therefore, I decided to go with green. I just randomly put on different color to get the color break up then I played with the opacity. I made sure that I did not have extreme light and dark area in my color map because I want the actual light to play with the highlight and shadow I spent some time to texture the scar on the body to make it look like a wet, fresh scar. I had to combine the spec, bump and color map to get the look that I want
This is the most fun part of making my orc! I spent about a day to make around 15 to 20 face shapes. I use blend shape library when modeling it because I like to see the default shape and the shape that I changed all together.
For the rigging part, I only made a simple rig for him for posing purposes. I did not spend much time properly weighting him. But I made a rig for his chains instead of using dynamics ( for a much better control in posing him).
I used diffusion to fake SSS. I really like the result.
Finally, for my final shot, I used only 2 spotlights. One really bright back light to bring the silhouette, and one key light. My T.A. actually did this render for me in XSI 4.2 since it has the new glow feature.
