Quote - with goz in Poser and it did create a workable morph, but  not yet sure what happens if you save it.  New to this myself.

Chances are, it's not going anywhere. This imports genesis for use in renders. Genesis is not native to Poser so you won't develop content in Poser. See if you can save the unsubdivided morph you made to an obj then use Morph Loader Pro to add the morph into Genesis. If you had just loaded DS4 Pro and used GoZ there, the resulting morph would have been added back as a morph dial that you could save and load into Poser.

Dimension3D also has a tool for loading genesis morphs, but I'm not sure how that would work, considering you could make a morphs specifically for V5 rather than the default genesis and in order to distribute the morph you have to use Morph Loader Pro "Reverse Deformation" option to extract just your changes to a morph dial.
