Quote - About the eyes I have to say that separate right and left mapping is not needed only for special effects... Eyes are not always exactly the same. I always add different small details on the iris, that gives the textures a small asymmetry that adds a realism detail...

How about a shared texture map and two separate materials for left and right then? That would give people the choice of making one texture map for both eyes or separate maps for each.
