thanks bis :)

just for the record I have experimented with shadow min bias and other settings, and the bias seemed to respond the most, and it usually had to do with either geometry too close to itself or another/or transparencies, all involving infinite light, and I use infinite light a LOT (hint: the SUN. aka: Ra, the sun god...). But I couldn't eliminate the problem at all, until I went back to pp2014 and it was entirely gone.

I know PBR is a thing these days, but its very much based on gaming tech from what I understand. Games are based on real-time performance. I'm more about photography style art. I have frequently considered Octane, tried it several times, but that's like a MILLION dollars per license I might as well dust off my Canon EOS... I might still do it if I have the money. Its just that Octane is not integrated into Poser like FF or SF, and it will all just slow my workflow down.

Also, Firefly turns out to be faster than SF believe it or not... regarding CPU. If you want to get the same sharpness ad FF in SF using a CPU render, SF takes way longer. SF does handle the light more realistically, but for the amount of adapting needed to achieve this, its hardly worth that little extra detail. Remember that we managed to entertain people with lined hand-drawn comics for decades, if Firefly in its acceptable mediocrity achieves an acceptable level of suspension of disbelief, its a renderer well worth working on.
