I have a problem with the graininess that appears in the shade. I want to render an object with a nice and clean shadow. The result is a
png with a transparent background.
Cycles engine. I have enabled Shadow Catcher, Transition, RGBA, Denoising - OpenImageDenoise . The number of Samples is 1000.
Can I fix this problem somehow?

This may not be ideal, but I solve this issue by passing the "Alpha" from "Render Layers" through a HDR Denoiser, then use the denoised alpha map to blend with the background image to generate the noise free shadow.

I was dealing with the same issue in a very similar scenario, I bumped up the samples to 2500 and used NLM denoise.
I tried many other tricks and variations but to this date, couldn't find a better solution other than just using more samples.
