UPDATE: after talking to a couple people, it looks like this could actually be described as a by-product of having my lightmaps TOO high…? Which confuses me. Lower lightmaps certainly obscure the problem areas here, but what if you need more resolution in order to resolve light bleeding, or pixelated light cuts…? As I mentioned, I’d really expect the “indirect lighting smoothness” setting to have an effect here, but it didn’t seem to. Are there other settings I could be missing that would help with this interpolation?
