I've got a question regarding noise. There's too much noise in my last renders and I am wondering how I can reduce it.
I'm guessing it has something to do with my area lights settings. There are 18 windows in my scene and I put an area light in front of each of them....so I've got 18 area lights. In the area light settings I've set the High samples to 32, high sample limit to 2 and low samples to 8.
Would increasing these settings reduce the noise? I'm a bit concerned that it will increase my render time by a lot.

Maybe there are other settings that I can change to reduce noise as well. Any ideas would be greatly appreciated
