Could this be the reason?

"Poser 13 is almost here, and we're excited to share with you some of the new features and improvements that will be included in this latest release. Unfortunately, end-to-end support for unimesh figures will not be included in the initial Poser 13 release. We understand that this is not ideal for content creators looking to seamlessly interchange data with other 3D design tools. To help with this, we have been working to improve Poser's design tools to simplify tasks such as creating clothing for figures. Fortunately, end-users creating scenes, rendering images and producing animations will not be affected and will find plenty of cool new features in this release."

Cloud be, it certainly shows some work was done in that area.

 

 

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.
