It does seem that, even if possible, there would be a great deal of effort required to get Genesis into Poser and to what end.  If Genesis is indeed better, I say if as I have seen nothing yet to suggest this a massive improvement, I doubt the effort would be worthwhile.

For most hobbists this would be beyond their skill set, even if they wanted to, and it seems the people in the know professionally can't see a need either.  That would leave it to a very small section of people to attempt it just as a challange while most would prefer to render with what is available for Poser without all the fuss.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
