When doing stuff in Source FilmMaker, I've decided the lighting of a custom HWM-style Team Fortress 2 model's head is weird when using multiple flexes, and decided to try re-exporting it from Blender and then re-compiling it. But something's wrong! http://sta.sh/02fvdp6o4yal

The model has lots of bodygroups (a total of 64512 different combinations, or 6x4x6x14x8x4 bodygroup options), set up by splitting the model into lots of different objects, and making lots of groups for each object so it can be combined with other related pieces as one wishes.

Yet, a thing consisting of three objects may work perfectly well, despite the same three objects not working in their own exports by themselves. The affected exports have no bone data at all, besides vertex group assignments of mesh vertices. (If they do, they're not read by StudioMDL, and Blender gives an error when importing them.)


This seems a lot like a return of that issue long ago with making a scene export where a group consists of only objects that have already been exported previously in other groups in the same scene export.
