I've been working for a few hours on a building model, composed of A LOT of different meshes (I just hate making a big one, cause I just can't put my UV correctly on one big model). I imported it in blender, looks good, but when I do some lighting build, it says my Ovject's UV are overlapping by 1.3%. I checked, it did create the lightmap, and it did apply it correctly. Only 1.3% ? I do'nt understand.
Hope you can help, Cheers

All the information you need about this can be found here: https://forums.unrealengine.com/showthread.php?748-Error-Lightmap-UV-are-overlapping-by-40
Additionally, if your uv's are overlapping themselves or are inverted, even the auto generator cant fix it.
It looks like either your UVs are still overlapping, or your lightmap resolution for that object is vastly too small. Try increasing the resolution and see if that helps.
