I finished the model then i did the blend shape (facial animtion).
After this two step i work on UV mapping,


When i play the time line, problems happend...

All the texture is a mess...

Does anybody know how to fix this problem?
I do not want to redo the facial animation again and i want the UV do not in a mess anymore.

I have tired to open the input and output connections in Hyypergraph Hierachy,
i suppose it can let me delete the history individually,
i deleted the history of editing on UV,
the UV is still a mess.

Hopefully you can give me a hand.
Cheers!
