Quote - Scripts might be able to take advantage though of zones named something like Body_Skin, Body_Nails, Head_Face, Head_Lips, Head_Brow, etc.

Well, "might" just doesn't work with me. :biggrin: Materials in existing figures aren't named that way, so scripts that look for that kind of pattern don't exist, and won't in the foreseeable future. I think unnecessary qualifiers make the material names harder to read. Scripts can be fed lists. It's not like there are thousands of new figures every day.

That refraction thing would indeed be a reason to have a separate cornea. But again with the "might". If no one's ever done it, why not keep the eye simple and let people make their own eye props if they want something more fancy.
