With the fitting room, almost all the products created for Genesis 3/8 are available for your Poser figures if you are willing to do a little work. I convert high-quality clothing, shoes, and hair all the time (dForce hair being the exception). A dForce garment exports like anything else from DS as an obj. Load and rig to the figure of your choice. Use existing analogues as donors in the setup room. With Headshop and body morphs, you can replicate almost any Genesis 3/8 character to a Poser figure (La Femme, Genesis 2). La Femme and Evolution have face rigging (and judging from the DAZ galleries, nobody uses it on G8 anyway). The possibilities in Poser are endless if you use the tools it gives you. Or just switch to DS and be done with these discussions.
