Mighty bold of you to think that vendors are willing to learn any new features in Poser, randym77.  Historically, too many are aggressively uninterested in taking the time to learn new features - especially if the end users aren't willing to use them either.

Lighting/rendering has been an issue in Poser since at least Poser 5 that I am personally aware of.  The Poser team in the past worked under the assumption that Poser end users have a photography background.  That hasn't changed, apparently.

Until there is a 1-click firefly-superfly conversion process for ALL materials, superfly is irrelevant for a lot of users.

From my perspective - This isn't Poser 13. 

It is Poser 12.1.
