I am using Unreal Engine 4.27.2 and world composition. I have sub levels. I couldn’t find any specific documentation about building lights in sub levels. All my lights are in the persistant level. So when I build lights, do I load all the sub levels in and build lights or do I do each one separately? It’s not very clear to me on how to do this.
Yes, with World Composition you have to load all the sub-levels in your Persistent Level and build lighting. Technically, you can open up the sub-levels and build lighting in them, but if there’s any additional level transforms when they’re loaded in your persistent level, the built lighting will be invalidated. You’ll also pretty much lose the Volumetric Lightmap for all of your sub-levels.

I took a chance and did the above while waiting for an answer and it worked! Your reply confirmed that is the way to go! Many Thanks!
