I have halted this project for a while due to a Poser bug where the Morphing Tool cannot paint weights over JCMs with the figure posed. Since all JCMs are created with the figure posed, you can imagine that was a problem. I had a quite long discussion with SMS about this until they finally understood what the problem was, and it apparently will take even longer to fix, for they say this code is quite complex.
Thankfully, last night Larry Weinberg (original Poser creator) has come up with a manual workaround that works. I first manually convert every instance of the JCMs into post-pended, then convert the outfit to Unimesh Skinning to force the Morphing Tool to weld the groups, RESET the morph (very important!!), and then recreate the JCM shapes from scratch. When finished, I convert the JCM morphs into pre-pended, then convert the outfit back to Poser Skinning, and move something to refresh the morphs. We can't see any changes before we do so.
It's an exhausting manual process, and I had to do it 4 times - one for each of Dawn's leg posing JCMs. NOW I *finally* got clean and sharp JCMs for the more extreme leg posing. The 11.0.4 update (SR-4) is coming out in a couple of days, so fixing this will have to wait for SR-5. It will NOT be fixed in previous versions, so I am officially retiring my beloved PP2014. So if you are creating JCMs for an outfit and notice some faces will spike out between body groups, refuse to weld and show artifacts between groups, or you see a quite visible pinching between groups, and you can't fix that no matter what you try, you will know it's the Morphing Tool bug I am describing here, and the above is how to deal with it.
So here's the fully fixed and working version of the bodysuit with all the bells and whistles. I have redone these JCMs so many times (before I knew there was a bug) that I have been dreaming about them at night. LOL
PROGRESS, YESSSSSS! \(^___^)/
