Fen (chemicalcrux) changed the status of T90974: Imported obj is 100x bigger in Blender. from Needs Triage to Needs Information from User.

We will need more information. Are you exporting .fbx files from Maya and importing them into Blender? If so, then it's possible that Maya and Blender are expecting different units (centimeters vs. meters).

I believe this is intended, albeit surprising: deleting the object just unlinks it from the scene. It still exists, just without any users.

That behavior occurs in image editors because you can't have a pixel with a brightness of more than 1 -- that's the hard upper limit. A Multiply layer multiplies the values of pixels together, so, in that case, you do always darken.

It looks like it's importing the bone as an empty, rather than creating an armature with a single bone. It's definitely something specific to the .fbx: if I import the .dae and export an .fbx (with no leaf bones), that .fbx imports correctly with a bone.
