Yes, I think you got it right.

The easiest way would be to load the OBJ from which you made the morphs as morph target too and set it at -1 - that should correct it. Most body morphs in V4 are hidden so you cannot apply a partial body morph. So just subtract where you started from.

A ship in port is safe; but that is not what ships are built for.
