Small bug or something that can be improved:
If I have a FP with some objects loaded in via the Library, and I have those objects come in to the scene as xrefs rather than embedding into the scene, and those objects are not in the same units as the scene, every time I open the max file there is a scene unit scale mismatch and I have to hit "ok" for every object, which can take a long time to do if there are lots of them. It looks like the FP/max scene isn't "remembering" that you are wanting to rescale/adapt them all to the scene units.
Thanks,
