1.11 Skin Editing, HELP!

[ddftrick]

Well I was currently halfway done filming an hour and a half WoW movie when 1.11 came out and possibly killed the entire project. I had skin edited all my characters clothing to give them custom costumes but now the customing doesn't work anymore. Has anyone figured out how to edit skins in 1.11 yet? If I can't get those costumes back the movie is dead and almost a year of work is down the tube.
