Lightmap looks blotchy. Rings of light.

Question

As you can see, rings of light are visible. I suspect it might have something to do with texture settings but I can't be sure.

I found the problem. In the lightmap settings, the textures were set to be compressed. I unchecked this option and that fixed the problem.
