I really don't want to put a damper on things and if you want to play my advice would be to go for it.  If you are undecided then I would say hang fire a while.   Some of us are having problems where the image maps are not being found once you have set up a R3 render and closed and relaunched Poser.

The only way to correct this appears to be to individually point the R3 material editor to each image map.  To make matters worse the default appears to be the Poser Runtime.  In the material room in Poser if you select a image map and then try a to change another it will go back to the last folder you accessed.

I am sure these problems will be fixed and I have been pleased with the renders so far and it has potential.  That said, for me, if I have to nake changes the process alone is longer than some Firefly renders and that is before you get to Luxrender.

I not trying be a kill joy here and I am trying to be fair but I do think if you are undecided that you should have as many facts as possible.

 

On a more positive note there has been an issues already noticed and already fixed with an update iminent so they are working on the bugs.

 

 

 

 

 

 

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.
