Trying to get materials correct for Superfly optix, and I have to say it sure is a big hassle ! Spending allot of time setting it up .... I really miss that Simple material room to make the basic setup ! Trans Maps, glowing maps, Bump maps .. everything needs to be placed step by step manually searching nodes through a load of options ! 

Superfly tedious work still building it up

Firefly fast work 

at the end the larger difference is the time spend for getting it right but both engines give very similar results, only difference in these renders are caused from the light, so wondering if it is really worth spending so much time making setups for Superfly if you can get the same in firefly in no mentionable time.
