The problem with V1 and V2 is that the files are not mathematically symmetrical. Daz wised up with V3 and made her symmetrical. I see no good reason why the earlier victorias are asymmetrical either, they clearly weren't going for a deliberate asymmetry (it's too close for that), it's just sloppy like some of the textures are. I never got around to doing the code to make my program work with V1 and V2. It's too much work for the amount of free time I have. The logic to pair V3's vertices is a straightforward quicksort on 3 indices, but with V1 or V2 I would need either an external pairs file or some kind of slow pairing algorithm that uses increases the slop tolerance until all pairs are matched. The later solution would not only be slow, it might also produce errors with vertices that nearly overlap.
