Hi, after some testd with SSS and fog i tried for the first time to render an interiorscene with octane. I built and rendered this scene in C4D. I used this scene, because i wanted to compare with the original image made for the 432 Tower in NY.
It rendered on a GTX780 for 2:12:12 and was stopped at 8200 samples. There was a lot of heavy noise on the fassades of the skyscrapers, which might look better with more visible lights and windows. But this is no artwork, this is an interior test.

I guess the original image gets alive by the spectacular, wide view over Manhattan. So my doesn´t.
