Hello Corona Renderer Team,
Recently, I noticed strange behaviour of Intel CPU/ GPU AI denoiser. The level of denoising is dropping randomly, even when rendering the same scene twice in a row without any scene actions.
Here is a 20 minutes preview, all Corona settings are intact for both images. Image A has a desired denoise effect, image B is the exactly same settings but visibly lower quality. This randomly happens only with version 11, without and with hotfix installed. When I render image B again few minutes later without any scene changes, I get the same result as A.
FYI, Corona High Quality Denoiser works perfectly but at a time costs.
