How to mix realtime and and baked lighting?

I am trying to make a scene for my game that appears to be completely lit by emissive materials. However, I have been having some problems both with getting the lightmapping right and combining the lightmaps with dynamic lights so that the player is lit up but the environment isn't whited out. Whats the best way to acheive this? I will add a picture. I also have an issue where parts of the wall do not get lit correctly, and turn out to be a separate color even though they have the same material. Note that they are separate gameobjects. I have shown that in the picture as well.
