Hello i have a problem with noisy
what typical settings need to use for interior..
1- i have 20 torches with Spot lights
2 - i have GI outside
3 - sun from windows.

How optimal to set this for reduce noise?
its will animation not just stills.

For the torches I would suggest you to definitely use geometry lights, I am working on a shot where I have thousands of light objects and it works really well.

I hope that helps.

Also for the sun from the windows I recommend you to utilize the portal light. Each window should have one.
