I have an issue with building lighting in Unreal for my project. It would always come up with WorldInfo_0 Maps need lighting rebuilt or WorldSettings_1 Maps need lighting rebuilt . The error message comes up every time you try to build lighting.
It is recreate able if you make a new first person project. Then turn on the setting in the project settings menu “Allow Static Lighting” which is located under rendering and then Misc Lighting. Then go into the World Settings and turn off “Force No Precomputed lighting” Then put a point light into the project and in the Details tab set the light to Static From Stationary or Movable. You should then build lighting and It should fail.
