Also, those are some really bad lightmap UVs. Lightmaps generally handle stretching and distortion extremely well so in order to get the most out of your lightmaps you should be laying them out as rectangles as much as humanly possible, snapped to texture pixels and packed as well as you can. See the UE4 documentation on it.
