Figured I would post my progress to this point. I have spent all night working on the iris for my alien. I tried other colors, but decided to go for an exaggerated version of my own. Damn this one is hard, probably the hardest thing I have done yet. This network is quite complicated in that I have ramps going into ramps and fractals that took me forever to figure out how to smear in an outward fashion. Turns out it was really easy. Just had to bring in the place2D texture node and stretch the fractal texture :)
Anyway, I have run into a big problem that I have not been able to solve yet (Working on it now) I applied a Bump to try and give the feeling of depth that the eye has but it causes the specular color to become all distorted. Hmm. Time to take a short break and think about it… Maybe I'll jump in the class room for ideas.
Work in Progress
