too much light causes noise Usually happens the opposite.. but today I have too much noise caused by too much light! (at least, I suppose It is because of that...)



I have also Volume scatter and absorption applied to a cyclinder that surround an area lamp





Here my setups:



light:



and there's also an environment texture:



It is a part of the scene where all the lights are on for a while:



any idea on how to get rid of all this noise? It occurs only when all the lights are on.. as You can see from this render (same samples)
As cegaton suggested, I've increased the number of samples (doubled) and the noisy decreased so much!! :)
