Hello all!
I can't figure this out so any help will b appreciated.
I created a 'thin' cloak .obj without hood in MD. Uvs excellent.
Imported it as accessory in CC3 and placed on character. All looks great.
When I try to weight it as 'cloak',  a portion of it gets ruined, stuck on different bones. I guess because the "cloak"  CC3 weighted category creates weights on other lower bones.
Then I can "custom" weight the bones and paint/remove all the weights besides the shoulder but the problem is that the cloak mesh is destroyed already and not only that, removing the weights from the lower bones creates holes/missing and double faces on the mesh/cloak.

I hope someone can help with a work around to enter custom weights without the mess being ruined already. 
Thank you in advance!
