Lightmapping light waves

Hello,

I am having a few issues with my game’s lighting (a potential affect of lightmapping). I am fairly new to the whole lightmapping game, so maybe I am screwing something up here?

In this first photo, you will see waves of lighting reflections / shadows or whatever that may be. And in the second photo you will see significant waves of lighting on the ceiling and the theatre screen.

Here is the second photo:

Thank you very much! I hope this turns out to be an easy fix.

Here is a snapshot of my lightmap settings.

I understand that these values are on the lower side. However, I’ve attempted to double these parameters in the past with no avail. Any thoughts?

As you are using an indirect light source in the scene, increase indirect sampling in lightmapping settings to get the desired output.
