Lighting out of Control?

The shadows and lighting are a little out of place, I used the Architecture assets, two walls next to each other, and floors on the ground. They all are giving off very Odd Lighting and Shadows that I am having trouble Understanding how to fix. Anyone help?

You need to increase the lightmap resolution of those meshes. Check here for more info: A new, community-hosted Unreal Engine Wiki - Announcements and Releases - Unreal Engine Forums
