Procedural eyes

Postby joepal » Sun Dec 06, 2020 3:19 pm

I've been amusing myself with trying to create fully procedural eye textures that fit both the high poly and the low poly eyes from MakeHuman.

These are the results so far. With the texture it is possible to vary both colors and the size of pupil and iris.

Same procedural texture, but colors changed around to brownish:

And for comparison, the "light blue" image texture material from MH:

And the very messy node setup. And this hides much of the mess in node groups:

Much of the complexity here stems from there being two eyes in the same UV. Thus many of the details have to be calculated as distances from specific coordinates.

I'll have to clean up the nodes a bit, but in some distant future, I think this might end up as an "enhanced eye material" in the same that there is an "enhanced skin" in MPFB.

Right on, I absolutely love procedural materials, and look forward to seeing more on this :D

Looking goodl For photorealism, it would be great if you could build in a way of handling "catch lights".
