Hi all,  
Just started to test lumens recently (yeah yeah I know, came a bit late) and I didn’t find how to handle all the noise I get from it. Right now I’m only using sky and sun light (no emissive or other types of lighting just for the testing).  
Where does these noises come from and how can I get over them?

We have big plans for improving performance, full Hardware Ray Tracing mode, less noise an…
