@mpro

Thanks! Interesting problem.
It seems the issue is only present when denoise is active. Otherwise works fine on all CPU & GPU modes.
Let's see what the devs say about it.

Hello Indigo team,

This issue has raised before. Noise reduction does not work most of the time. It's not a scene issue. It's not an Intel issue as it does not happen to other renderers who use the same algorithm, it has something to do with implementation.

I would appreciate taking a look.

Best,

K.
Hi,
Preliminary investigation indicates that this issue is due to having very small values in the render buffer.

For example, from pick info: HDR sRGB pixel colour r=1.7974841e-12, g=1.3779304e-12, b=1.3725927e-12, a=1

The issue goes away if you make the emitters much brighter (and can then turn down the tonemapping scale).

I'll look into it some more though.

@OnoSendai

Hello,
Indeed this solution works, I have to further try that in different scenes but it seems like small values in lighting cause the problem.
Thank you very much!
