Hi I always have noise in shadow pass while other passes as light mix, lights and reflections are noiseless, how to get rid of this?

Thanks for the support.

Do you have denoising enabled for the shadow pass?

I do not have denoise for any pass for this specific case. But had the same result in other scenes where was active and flagged in shadow pass.

Did you ever work out why this occurs? I have the same issue time and time again. In fact I don’t even do a shadow pass anymore as it’s totally unusable.

If it's a repeating issue, I'd put in a bug report (with version of Corona, version of C4D, example output, and preferably an example scene) - see https://help.c4d.corona-renderer.com/support/solutions/articles/12000033461-how-to-report-issues-c4d

I noticed increased fireflies (looked a little like the render above) when the "fast caustics solver" was enabled - might be worth a try.
