Lighting needs to be rebuilt error pest

After building the lighting every thing runs fine with no errors. I’ll then save the scene and exit UE4. I’ll then run Unreal 4 and load in the map I saved and when I play the map I now get a Lighting needs to be rebuilt for X number of objects.

Any ideas why?

I have this same problem!

Are you perhaps modifying static meshes using a construction script? Anything that changes their transforms or settings could be marking them as dirty.

no… not doing anything special… its just lights ,static meshes, and decals.
