Hi all.
What could be the reason for this noise? This has not happened before. Occurs when i add the light to my scene

I'm using PT Kernel. But same issue with DL / Diffuse Kernel
Updated the final ver. of LW plugin. Same issue.

Thanks in advance.

It seems specular or sss noise. Have you tried to remove it using the hot pixel visibility parameter in the imager node?

Thanks,

Set GI clamp to 1.0 instead 100000000000

Thanks for replies. I decreased the clamp. But same issue again.

I guess, problem is in my material setup.

It is interesting, when i deactive the material mixer and universal material, hot pixels are gone. isn't it strange?
