What version are you playing? This is already fixed on the latest 0.8.2 version (not 0.8.2b, the latest version of 0.8.2 itself.)

it was not fixed in the last 8.2 update for sure, many models wouldnt load, but also a bunch would. they were all configured the same way on my side of knowing how to mess with the files. either way i accidentally deleted that save like an hour ago right after cleaning up the third transformer fo trash, so I'll see in a bit now if it works again in this new save. but not all meshes seemed to work before, like they did in .7
