I took a very detailed look into the eye of a human. I noticed that it almost has a “hair” look in the iris itself. I decided to actually attempt to re-create this. I did it using rather simple splines and rotating them.
Simple half sphere with Diffuse texture (veins with bumpmap) radial opacity map and reflection raytrace of 5.
A black sphere. With hair looped around it. The hair was a simple “frizz” style. Then turned to mesh. The mesh then had another radial texture added to it.
I think it looks fantastic! It’s a great to do a nice close-up on something so simple as an eye.
