So if Majority just wants " Render Cycles " Texturing  you might as well cut down poser to a Material room , would not be a big step away as already quiet some features gotten removed, Poser might even end up as a great  Substance Painter. I rather think that the major fun part in poser is the posing of assets, and these actually should be the main discussions rather then loads of confusing texture nodes

Keep the Texturing simple but make the Models great and Complex, with good articulations, as you can not make a crappy old Model better just by using render cycles. But there might not be any other choice then to make better textures for the old models as there are not many new ones. Actually the point where you should start making some changes.
