Noise level limit and denoising issues

[smid1584]

Hi,

What is the relation between noise level limit and denoising ?. When denoiser is enabled with noise level limit the render take very long time in each pass to reach the noise limit ( it takes forever I usually cancel it )  but when I disable denoising it works as expected. As I understand the denoiser is just a post filter calculated after the render is finished isn't it ?

Hi,
the denoiser actually changes the image sampling algorithm slightly, so that less time is spent on regions where the denoiser is effective (and vice versa). What you are describing sounds like a bug, could you upload the scene so we can have a look at it? You can use our private uploader: https://corona-renderer.com/upload
