Lighting in a post-apocalyptic game

Hey everyone. I’m currently designing the map of a zombie survival game like DayZ or H1Z1. I made a few houses but the problem I’m having right now is a lack of lightning. I searched on Youtube on how to provide good lights but none of them tell me how to light up the insides of a house or apartment building with just sunlight. The insides of the houses I built are basically pitch black. Can anyone point me in the right direction on how to create good lighting with just sunlight and no other light source?

When you just want to use the sunlight you will have to enable gi. Otherwise add a skylight. :slight_smile:
