Render shadows without denoise on a transparent background in cycles 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.
Render in 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 &quot;Alpha&quot; from &quot;Render Layers&quot; through a HDR Denoiser, then use the denoised alpha map to blend with the background image to generate the noise free shadow.
