That's what I heard...IIRC for destroyable-subobject 'fighters' that were 'parked' in/on hangar bays.
Unfortunately it doesn't look like it's implemented.
If I understand the code correctly I might be able to add that (It's certainly possible). I'd like to hear from Bobb whether or not it's implemented though.
If I were doing it, though, I'd basically find the distance between the subobject's position and the viewer position (Unlike the code for models as a whole, which finds the nearest point on the mesh) and set it accordingly. I make no guarantees though, it'd be my first time working directly with the model rendering code.
