As far as I know the figure simply will never work with Morph targets after you replace the .obj ... morph targets depend on exact polygon counts and positions - the one thing a subdivision is guarenteed to change. You would need to morh your figure FIRST, export the .obj with the morphs applied and then sub-divide. These subdivided figures are not replacements for your Poser figures. NOTE: I didn't write poser of this utility so I might be wrong, but I don't think I am.
