Hi. I have a scene in which a single floor tile is not receiving the proper lighting. The prefab is exactly the same with no changes whatsoever, but it looks distinctly different from everything else. I've tried to change a bunch of settings and regenerate, but it always looks like this. The "realtime lightmap" field on the renderer also looks distinctly different, like it's not receiving light from some of the sources in the scene. What's going on here?
