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.

This sounds good. It means extra materials but not neccessarily extra textures. pitklad is quite right about the symetry issues and I do a symetric eyebrows but myself am too lazy to do asymetric irises.

I rendered that Posette-3 at 2000x4000 and it actually looked even better... the key to working with Posette are the expression morphs on the old characters from Japan which also have lip and eyelid fixes and Stahlratte's fixes for the edges on the brow, nose and lips (available at Planit3D I think?). Posette rocks because she is so light on overhead and can look really good. Working with the V3RR and M3RR has made me realize how important topology is above all. Those V3/M3 shoulders though... ugh!

Here is something I have been wondering about odf... I still am not clear how you are releasing Antonia but can the ankle area and maybe feet be released in such a way that people would permited to build sandels integral right on them and use geometry switch injection for the shoes instead of conforming -- like those Bratz Dolls for kids where you change the whole foot instead of trying to fit shoes on. Kirwyn released "K" with injectable geometry switches for shoes and it is delightfull not to have conforming issues, not to have loose fitting straps and poke through, not to have "Big Shoes".
