As an aside, if you are feeling precious about a FBM that you created on the mesh (from Geometries) but accidentally dumped the grouping info, you can still use that morph.

Import the figure mesh from Geometries into Poser as a prop.

Apply the grouping dumped FBM obj as morph target to the prop (properties Load Morph Target)

Dial the morph to 1 on the prop mesh

Export the prop mesh (which has grouping info intact) with morph applied and active as obj with only "include existing groups in polygon groups" checked.

Load FBM to figure using the new obj you just exported.

Result: resurrected FBM from obj that had lost it's group info.
