Generally I do not have a problem with V4WM and the perfect fixes, depending on the pose in question I might have to change the degree to which the fix is applied.  That said I tend not to do 'pin up' but a lot of my Sci-Fi renders have some very tight clothing on my V4 figure and she does get herself into some really strange positions and scrapes.

 

 

 

 

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.
