I have a problem here. I made a map on blender and imported it to a 3d person template on ue4. Its all nice and I can run around my map with adefault character. But when I press Build lightning, the map becomes completely black. I left all default lightning components and settings. I tried to apply texture to my map but same problem. Nothing I tried helped. And on my phone its just a dark screen with only control sticks visible. Mobile HDR unticked and optimised for android.
Now I dont remember having this problem on 4.2. Can someone tell me how to make the map to stay lit after lightning rebuild?
