I keep seeing this question come up time and time again, what causes waviness? How do we fix it? I feel the reason it keeps coming up, is a fundamental lack of understanding.To get to the root of the problem, we have to look at how normals are averaged, and thus, how the actual rays that are doing the "baking" are cast, and in what direction.

I didn't find the right solution from the Internet.
