The real point was that, if a pose does not contain BODY transforms, and any x or z hip translations are not to large, you can use the BODY transforms to position the figure anywhere in the scene, in any orientation, at any altitude, and applying the pose will not significantly change the location of the figure within the scene.

That's two big IFs

And like I said, that's what I what was doing. But I got tired of having to rotate the characters.

Actually making it all one big OBJ prop may not be a bad idea, just not ALL of it, I'd leave a managable number of "loose"(animatable)  props...

hmmm...
