The real big advantage of Dawn over V4 as far as I can see is how easily it is to produce natural looking expressions. Just how much this is important to user will vary but I would think, while bending would be important to those that do 'pin up' type renders, having a good expression would also be of value. The morphs available around the
forehead are extensive and add to confused or sorrowful expressions but even the ability to generate a smile that does not look like that of a crazed killer is a real benefit.

 

 

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.
