Title: Light Noise
Post by: PinkBubbles11 on 2021-06-10, 14:45:16
Hello! I have a problem with the excessive noise whenever I use artificial lights in my scene. Does anyone know why this happens?

By  any chance you have a self ilumination on those lights? is fo try lowering  the intensity
If its just ies, try another ies file, or try to lower intensity, if you were using light mix be sure to transfer the lighmix values to scene.

Are you by any chance using LightMix here and boosting light intensity? (dim lights which are boosted using LightMix)

I am using LightMix, indeed. Should i adjust each light from the modify panel and set lights value in light mix at 1?

thank you for your response! I am using Light Mix, indeed. Transfer then into the scene, as in adjust the intensity level on each individual light in modifier pannel, rather than using light mix?

1. Make sure denoising is enabled for each LightSelect layer
2. Make sure you are not making changes that are too large in LightMix, e.g. reducing or increasing light intensity by a factor of 10 or more as a very general guide (you can often get off with using larger changes, but that does depend on the scene, so if you are making adjustments larger than that do some tests to see if that is what is introducing the noise)

Hope this helps!

Kinda looks like you have a displacement map over the wall and its causing that.
