There is practically zero information on the ORBX export limitations in the documentation, or how to optimise or do practically anything with this. Can we please update this?
I'm having a nightmare trying to export a scene with a packed alembic which is about 900mb on disk. When I try to save the scene to ORBX with only this alembic inside, it turns into a 14GB file and takes about half an hour to save. This has been a long standing problem and I'm surprised this hasn't been addressed properly.
Does exporting animated houdini scenes as an ORBX just not work?
