This is Zbrush info but scroll down to Rebelmommy's posts near the end, she's explaining about bringing morph targets for multiple bodyparts back into Poser:

Quote - Well you can get the p[arts back into poser in 2 ways that I know of.  You can do as EddyL said and export each part seperately out of ZBrush by doing the following (again this is an example ofa Head/NEck combo) you select as visible the head (Ctr+Shift+Click on Head) and export the head, than Ctr+Shift to make everything visible again, then you select as visible the neck (Ctr+Shift+Click on Neck) and export the neck.
 Or you can export the whole head/Neck?ect obj out ofZbrsh just as you have been doing the individual parts.  Then you import that OBJ into poser using : Import>Wavefront obj.
Once it is loaded and selected in poser go to your grouping tool and select spawn props.  Then it will split your head.neck combo into 4 parts.. the original head/neck onj, a copy of that original and a seperate head and neck.  Simply export out the head and neck one at a time(with just the as morph target no world transformation checked) and then you will be able to import the new pieces as morph targets:)
