I did try the 'shape of a woman' product but it does weird things to the arms or at least it did when I tried creating a 5' 2" V4. I tried playing withjoint fall off zones and other things and then asked on this forum. Others had seen the same problem but were unable to fix it. In response someone sent my his own script to shorten V4 yo various heights. This worked like a dream and so I no longer use 'shape of a woman' . Not sure if it changes the proportions as I was only really interested in the height change.

I also use Shaderworks Advanced Figure Manager and select the "include scales when conforming" option before conforming the clothes. It works well and all I need for my character is a spin of one of the dials in the chest 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.
