Hi Rahulkirito,
I’ll need a bit more information about your scene first since this isn’t really enough to go off of at the moment.
- Do you get the same issue in a new blank scene?
- The unbuilt objects is 637 objects, so this is likely something other than just the sky sphere being black. Can you run the Console Command “DumpUnbuiltLightInteractions” and then in the Output Window (Window > Developer tools > Output Window) copy the listed objects there to a text file and attach here.
- What type of lighting are you using in the scene (Movable, Stationary, Static)? Is this just a directional light or other spot and point lights too?
- Is this happening in the viewport window for the editor or only when you launch in another window like you have shown in your image?
- Is this using the same default SkySphere that is from the Default scene in UE4?
Thank you!
Tim
