denoiser and regions

[BVA]

is there any way denoiser can work only on the rendered region?

Often when I rendered a full resolution image I might see something is wrong. Immediately I would render a region to fix that. This will keep all rendered elements except the denoiser will have a black image with only the region in.
Currently I save out the render, then render a region and in post I mask/ overlay the 2 images. This is a little unproductive but it works.

Hey BVA,

Thank you for the post. You can achieve the result as replacing the RGB file with denoiser itself. I've been attaching a few examples How - to do that and scene file. I hope that is workable for you.
