Lights go dark when rendering a cinematic

I´m trying to render out a cinematic sequence but the rendered material comes out almost pitch black. In editor mode everything is well lit and the camera view when making the cinematic sequence looks fine too. Only when I try to render it out the lights seem to disappear.

The cinematic is set in an apartment and there´s supposed to be a window with a view to outside but that disappears completely too.

This same problem occurs when I go to play mode. So I´m guessing it´s got something to do with a setup or the lights or the levels but I lack the knowledge of how ue4 works to try and find the problem so a little help would be much appreciated.
