I’m following BlenderGuru’s donut tutorial, and right now I am modeling the coffee cup. The problem is that the cup looks kind of foggy after rendering (see attached screenshot). There’s a weird black-spot pattern that’s present on the side of the cup and in the cup’s shadow. When I turn off “cast shadow” in the lighting settings, the problem goes away. This makes me think it’s a problem with how the light is interacting with the glass material and casting a shadow.
I’ve tried a lot of different ideas I’ve found online, but nothing has worked so far. Yes, the liquid is scaled up so that it overlaps the cup. And yes, denoising is turned on. Increasing the number of render samples doesn't help.
I really appreciate any help!
