Hahaha! Yes, that is why I added the caveat of "my very specific use cases". I can imagine how tangled things would get when you try to support even a fraction of what Blender can do. If I do make any discoveries though, I'll definitely share them. Thanks again.

Thanks for the quick response. I understand this is experimental but assumed that experimentation was ongoing. Is the current limitation for static mesh export a hierarchy depth of 2? If so, I'll just build my pipeline around that limitation or write a specific exporter of my own (for my very specific use cases).
