Rate my sweet eye I've just made. Isn't it cool?

Its not in VR 3d so why would we care?

its shit

It's too reflective and blurry.

Cornea is supposed to bulge slightly over the iris/pupil area. Iris is actually a flat group of small muscles and not curved like the rest of the eye. Pupil is the hole in the sphincter of the irish.

This is a terrible eye.

They're always after me lucky charms.

Allright model for non-main-characters or if only rendered from a distance, but if you want really expressive eyes that can be used for closeups, you'll have to model the cornea a bit more accurately than that.

It's quite important for expressiveness and the "jewel effect" that the cornea is concave, and that the translucent material on top of it has a high IOR.

Also, it needs to be rigged...

Pain in the balls to set something up like that and the clipping can be horrendous.

>clipping can be horrendous.

Why it is a good idea to use a normal map to create the illusion of a parabolic protrusion on top of a perfect sphere so the cornea don't clip the eyelid as the character looks around.

Yes, if you don't want to go through the effort and just give your characters passable eyes, you can get pre-made assets in many places. For blender, for instance, I tend to use the eyes from one of the blender open movies, like cosmos laundromat. Can always tweak from there.

using two pieces of geometry is pretty outdated by now, you should just use parallax offsetting if your software has the option

using additional geometry for occlusion is probably a good idea though since it can be hard to make it look right otherwise

>>521781
Don't know what you mean by parallax offsetting exactly, do you mean parallax mapping? If so, that's only really relevant to realtime rendering, for offline renders you can afford the extra geometry.

Anyway, I usually create one sphere and then a smaller sphere withhin it. Create an indent on the inner sphere (iris), an outdent on the outer sphere (cornea.) Give the inner sphere a glossy material with eye texture, the outer sphere a glassy material -- done. It's not a lot of effort and tends to look pretty good IMO. If I want really close-ups, I might actually make the inner sphere hollow and make the pupil a hole + add a subtle light that is rigged to the eye rotation that shines into the eyes that can be turned up/down to highlight the jewel effect.

sounds like you have some shitty Open Season tier eyes going on

There were 3 movies, and now a fourth.

Here's a cross section version I once made for a medical animation

Also consider the fact that the reflection of the eye has cubic distortion. There was a paper from activision talking about it, just cant find it atm.

activision can't make anything look real without doing extremely heavy mocap for the body and the face and then running simulation on the muscles. At that point, why even bother.

>>521905
Not entirely sure if we're talking about the same thing, but if you're raytracing/pathtracing, that just happens automatically.
