Radiance thanks for sharing your decision.
As customer what I'm expecting it's to be able to have fast, solid, and fireflies free rendering engine.
Personally I don't really care if the engine it's based on Mtl, Rtl, CCG, PFOGKDKEEKVIA or who knows.
i'm sure, 99% of your customer didn't know (like me) what it's really the difference between Mtl an Pt, but they look to see if the image it's cooked in time.
KEEP WORKING to create the first, stable, solid, GPU unbiased rendering engine!
