Updating Cycles, a possibility

Including Eevee, I doubt it.  Even in Blender, the Eevee engine lacks certain features that Cycles do better.

New figures?????

Universal Human, I also doubt it.

Superfly Material for V4/M4/K4.  Really?  Build your own; I have and many others have also.

Texture Transformer.  ATM, this application has stagnated where Poser is concerned.

Updating EZSkin.  What Material Room node combinations would you propose for the app?  There are various combinations I have generated on my own and corrected from EZSkin3.

FaceRoom is a dead issue.  It was taken out in P12 and it is most likely not coming back.

@TOTOBooth05: Did you ever post any of these recommendations in the P12 Suggestion Thread?  It's foolish now since P13 is currently in Beta testing.
