My team was using the Unreal Mannequin for the base skeleton, I am using Character Creator 3to quickly create a bunch of characters and everything was going fine, until the animation team needed to add bones for their work in Maya/MoBu and update the skeleton in UE4. Now all my characters from CC3 are missing those extra bones and causing some animations to no longer work in Unreal. Even if I try to use the updated skeleton when I export from CC3 and import to UE4

How do I get those added bones when I export from Character Creator 3 to Unreal?
