I, for one, love the remapped Posette's, cause there's only a handfull of good high res textures of the original map.  And I'm too lazy to make one for the old mapping.

V2 freebie maps are harder to find, but there are dozens of excellent V3 freebie skins - for those who rely on freestuff.

I have enough commercial textures which I can use on Posette like Thorne/Sarsa ones including their MillGirl ones which are V2 based.

V2 comes also with a V2P4 version means she can wear Posy clothes and it's now drastically reduced in price, so this can be an option for a higher poly Posette. Especially since there's a free morph available to shape V2's face into a Posette shape.

Now if someone would remap Posette to V4's UV - I'll be happy.....
