Can't generate UV Lightmaps for Custom models.
I imported custom models I made with MagicaVoxel, but even with "Auto Generate UVs" on for the import, after baking lighting the become completely black. In that mesh editor when I click on the "UV" tab nothing comes up at all and after trying to generate them again and again with different settings, nothing ever changes. Only UV channel 0 ever shows up.

ue4's auto generate lightmap uv's only work when there is already a proper unwrapped uv-map available to read from and rearrange the already existing uv's.
It cannot unwrap the mesh for you.
Additionally, make sure that the lightmap size is set correctly.
