I'm confused. It seems to me possible that a different UV mapping could require a change in the number of UV coordinates.
Most 3D vertices are assigned a single UV coordinate, but not those along a seam. Where there is a seam, each vertex gets two UV coordinates.
Now in an alternate mapping where the seams stay the same, and the UV's just move a bit, I can see keeping the number of UV coordinates.
But in a true alternate mapping where the seams move, if they move from one line of vertices with X points to another line with Y points, and X and Y are different, then it has to be that the number of UV coordinates is different.
And, if the number of seams changes altogether - well that's totally different.
Imagine switching from a V4 style pelt to a V3 style pelt.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
