I did this tutorial, and when I render there is an artifact like in the image below.
I'm using the last macOS with an AMD 560, and if I don't include denoising everything is fine. Can someone tell me how to solve this problem? If I render on the processor with denoising then everything is in order. How does the problem relate to the graphics card?
Or how could I set up denoising so that there would not be such an artifact?
