Hi, I have a question about the optimization of multiple characters for game engine export.
Ideally for performance, an ensemble of characters (for example, 4) wearing the same uniform, would share the same material/texture set for the clothing, and the same material/texture set for the heads.
For the clothing, this is possible to achieve in CC, albiet a pretty clunky workflow that requires collapsing items and merging materials, then saving the combined result as a new asset.
However, for heads, this doesn't seem possible without exporting to a DCC and repacking the UVs and textures manually.
This is essentially because head 2 3 or 4 cannot see or reference the UV mapping of head one, being that CC can only work with one character at a time. 
Does anyone have any insight on potential workflows inside CC for this? It is, I would suggest, a fairly critical shortcoming of the software for optimization purposes that I'm trying to solve for my team.
Thanks.
