What does this 'Lighting Build' error report mean?
So my 'Humvee' asset keeps getting this error report every time I do a 'Lighting Build'. So, what does this mean and how can I fix it?

This means your mesh's lightmap UVs have multiple UVs in the same place which breaks lightmapping since different lighting will try to be in the same place. This may be because you're using the wrong UV set. Most meshes want to use UV channel 1 and not 0 so make sure you have the right channel set in your static mesh settings. If your UVs in channel 1 are overlapping you can generate UVs for lightmapping whic is also in static mesh settings. Make sure the UV channel you're generating into is the same as the UV channel you're using for lightmaps.
