need advice to light up interior scene with deep space, illuminated mainly with artificial lighting. Everything is OK when there is a window in 2 - 3 meters, but when i need to visualize enclosed scenes there is a lot of noise, like in the example above.
this image was stopped at 500 passes, it is not much, but i discovered that if there is lot of noise after ~100 passes, it won’t disappear even after 1000.
in some cases i avoid ceiling in the composition and make all ceiling emit light. That works fine(clear render), but this angle isn’t suitable for this scenario.
would be great to hear some lighting tips and techniques, thanx.
