Originally posted by Christian Kugler what about just grouping it after all the changes are made? but if i group it will that still give it a history? might this work? thanks christian you need to global stitch history to remain on the patches. otherwise they will not be seamless. even if you weight them properly, the will break during animation or the tangents will not remain continious. global stitch is necessary for a patch model to be animatable [properly animated as if a single continious surface]. grouping them will not help.
