I totally agree with Rogerbee1 above, plus I personally think that due to the technology and people's overall increased knowledge and ability, that V4 textures are better than V3 textures. So if Antonia were to be remapped to fit a different figure, V3 would be too much of a step into the past.
And I personally think it would be tragic to see people using V3 (or even V4 or any other) textures on Antonia. Antonia is hopefully going to be inspiring future creativity, not merging with the past.

Speaking of textures and remapping....
Olaf, since it's been a good while since the last modifications were made with the new UVs, is it about time I put out a link for the general public so anybody who wants to try making new textures for the final version can have at it?
