Are the artifacts the dirt on the door glass? I am not sure. Can you send to me the scene to test it here?

One thing you can test is to modify the ray epsilon parameter in the kernel, to know if you have a precision issue.

Hi,

The problem is the quad light "finestra" that you have behind the window. It has a shape opacity of 3%, and this is what is rendering the artifacts. If you set the shape opacity to 0%, or you enable the unseen by camera flag, the artifacts should disappear.

Thanks,
-Juanjo
