Title: IES noise on large scale interior
Post by: Gtelis on 2017-05-21, 13:33:00

Hello.This might have been discussed before.
I am currently working on a large scale interior (floor plan of 21 offices) that will be animated as a walkthrough. Obviously due to the animation I need to keep everything tidy and optimized (portals, UHD cache, no emissive  materials etc).
I noticed a great noise increase after the first 5 areas I modeled, with the noise being almost exlcusive to the ies lights. So I tried to isolate each room and render using the same exact settings.
Am I doing something wrong with my light setup or render settings ?

So the noisy render is when the whole scene is rendered, and the clean one is when there is only one room in the scene? (other rooms are hidden?)

What is in the other rooms? Are there also lights in there? Is there some complex geometry in your scene with a Corona Light Mtl applied?
