Like others I do not have the knowledge of Python to be able to help out but I do agree that some changes would be helpful.  At the moment I am converting old content with the scripts that are available such as Go Physical from Ken1171_designs and what little knowledge I have of Superfly materials.  With the textures I have changed I make a point of deleting the PoserSurface as part of the process.

 

 

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.
