I have a large cube set up in a level with a directional light and the bp_sky attached. A building I have set up is lit on one side, but the other side is completely black. How do I make it so that the light “bleeds over” so to say. Or if I need to make multiple lights, which ones are good for this? Thanks!
You have to add a skylight 
Add a skylight in addition to the directional light.
Perfect. Thanks!
