I've managed to get 4 G2F figures into Poser only by working on them individually and loading them already posed and clothed.  It took quite a dance of hiding the other figures or working in wireframe mode to get them positioned.  Posing using dials is very frustrating as others have mentioned.

That's really impressive. Usually I have some G2 clothing or prop error crash my scene past two figures. If I use less G2 props and clothes it's better. Lots of saving the scene as I do anything.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
