The 'Perfect' series of fixes work with V4WM, or at least I have had no problems with them working.  I converted a 'virgin' version of V4 to V4WM and then added the fixes as per instructions that came with the fixes.  I used them at first when I noticed that the first version of V4WM had a couple of areas that I wanted to change.  There has been an update of V4WM since then, but they do work, how much you want to tweak them is a personal issue. 

Others will also say that they are not needed and increase the size of V4.  The first point I suggest is subjective, the second is true although I have not noticed any dramatic change in loading or render times and disk space is relatively cheap.

I also have Va Va Va Voom added to my main character as I used in in the non-weight mapped versions and wanted to copy my character as faithfully as possible in the V4WM version.  No doubt I could have done a copy without Va Va Va Voom and just used V4WM but I had the settings and it was a quick fix.

Having said all that I am not suggesting that the fixes are the way to go but since their use was questioned I thought I would pass on my experiences and I will not be removing them any time soon.

 

 

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.
