You need to include the offset a information for figures where the rigging has been realigned. At least I had to for Diva with her realigned rigging
In Poser Pro 11, I used File>Export>Morph Injection on my Poser native conversion from DS of Nataani (right) to create an INJ pose for Nataani's body. I added that to a fresh Dusk (left), injected the FBM, and dialed it to 1, then added the base MAT I created when I made the conversion from DS. Scaling the head to 107 percent captures your proportions. The closeup is of the injected Dusk.
This is what happens when you pose a figure without realigning the rigging...this is my dusk child morph that I haven't done the realignment on yet.
