I’m posting a very simple tutorial on how to model and apply shaders to get realistic eyes, the “windows of your character’s soul”. A lot of times, bad eyes can “kill” your character literally, even if it has the most perfect modeling of the world. The importance of the eyes is exactly this: give life to your character. Therefore, don’t underestimate this very important step of CG character construction… if not, you’ve only created “puppets”
There is a quite big camber in the cornea, in the iris area. That irregularity, that all of us have, can become a great problem for a CG character. When rotating the eye, this area unfortunately would invade the eyelids faces, causing strange results. For that reason, I decreased this camber to avoid a probable future problem.
Step 6. We will transform the extremity triangles…
Step 7. …in quads, cutting the mesh this way:
