So I've tried to get rid of 2 problems in my render. The first problem is found on the right side of the image at the door and window. I'm getting some weird aliasing that I can't seem to get rid of, and I have no idea why it' there or what is is - hence why I can't search for anything to fix the problem.
my other problem is that my picture gets super grainy in the back of the image. How can I fix that?
