If it’s me, I always model the eyes separately, then join them to the main mesh. Then, I select the eyes, and make them a separate vertex group.
I’m very sure that’s not the best way to do it, but it always works for me. I always model a hole/two in the head, then add the eyes, then position them as a separate group. I’ll try to get pictures
Well, I played with it and ended up doing it with two spheres. I still have eyelids to do, but we’ll see if this works. I just seemed that it’d be easier to rotate the eyeballs around if they were perfectly round.
you could always use the “cars” technique, where there’s two irises on one flat surface.
here’s a blend i came up with, maybe you can study it and see how it works. to move the irises around, move the two Emptys that’s directly behind each one. http://www.hammerdave.com/misc/flatEyes.zip
