Hello, when transferring UVs in Maya, it\'s important to ensure that both models have the same topology structure, otherwise you may encounter issues such as fragmentation or incompleteness. If your model has problems after transferring UVs, it\'s possible that the topology structure of the original and target models are different. I would suggest verifying that the topology structures of both models are identical before transferring UVs. You can also try using plugins or scripts to assist with the process. Hope this helps!
