I imagine there is some issue with worrying about copy right and licensing on some of those fixes. It would seem Poser would have to have a sort of open source license figure rig with those features including an optional use of a set of generic fitting magnets that could be easily adapted to different characters. That kind of goes back to licensing worries and problems for different figures. The fitting room fixes some poke through issues, but depending on the poses that can change.

On a side note, the new Blender eevee engine looks really nice and could replace ray trace preview renders as well as be used for very quick animation test renders of high quality. It's amazingly fast. It's still in development but progress on it is going quickly.

The dust settled, thinking "what a fine home, at least for now" not realizing that doom would soon be coming in the form of a vacuum cleaner.
