I agree with Jaager on this, morphing doesn't change the mapping, but it does exagerate defects, and it can also change the color of a map- I was trying to do long glove cuffs by morphing the Posettes' shoulders, if you "streach" too far white seems to get added to the color shown on the figure, perhaps if you compress them too close they go to black, I'm unsure of the later. I also know there are areas of the Posettes mapping where the vertices are just too far apart to let the figure map problerly when the joints are bent, the maps are not proportional in these areas.
