My light baking stopped from 0%, and it is never getting forward.  
When I click ‘Build,’ it shows me the message log that is saying, "World Settings\_Maps need lighting rebuilt.  
I’ve been waiting for 30 minutes, but UE4 crashed.  
I’m using AtmosphericFog, Skydome, ExponentialHeightFog, Post Processing Volume, Skylight, and Directional Light for lighting.  
When I change the view mode to Buffer Visualization Overview, I cannot see anything but Scene Depth.  
Can anyone help me with it?

Try it on an empty level.

If that works, try gradually incorporating what you have in this level.

Is that a very large landscape? Did you tweak the landscape lightmap res?

Thank you for the response. I tried light baking from another level that that works. I think it’s a problem at this specific level. I didn’t change any lightmap res if I remember correctly. I made a copy of the UE4 file and testing light baking by deleting assets one by one. I’ll let you know.
