c&c are very welcome 
an old project recently updated . cycles , 1200 samples , with some patch at 5000 samples in the most noisy spots . 2160x3940 , 3h50 rendering
Wow, interesting concept you have! But this noise comparing to such amount of samples is something outrageously, did you use clamping?
@yoraUT … it’s the bigbig glass with IOR enlighted only by bounced light
The overall concept is somewhat confusing to say the least, but it works because the effect looks to be intentional.
The only thing I can see that would improve this greatly would be giving it a few times more samples like already mentioned.
@ace dragon … it will take a whole day to render and i plan to do it in the moment when i can leave the pc alone for so long ehehe
