I have a level containing only a Skylight (set to Stationary with “Cast Shadows” disabled). Additionally, there are 36 Blueprints in the scene; each consists of a single wall mesh and two Point Lights. In total, there are 72 Point Lights, all set to Static. When I build the lighting, only some of the Blueprint lights bake correctly, while others turn out very dark. By the way, I do have a Lightmass Volume in the scene, scaled to cover the entire building.
Hello @AlkeyXXX ,Welcome to the forums!
I don’t know much about the lighting system, but it’s possible that the issue is related to the use of Static Lights, and that some of them aren’t baking correctly.
First of all, go to Project Settings and look for the Global Illumination option. If it’s set to Lumen, change it to None.
Then, in Project Settings, look for “Allow Static Lighting” and make sure it’s enabled . Once you make this change, Unreal will ask you to restart the editor for it to take effect.
After restarting, go to Build and select Build Lighting Only to rebuild only the lighting.
Keep in mind that when using static lighting, you’ll need to rebuild the lighting every time you make changes to the lights for it to work correctly.
If the issue is related to the static lighting configuration, this should allow all of the lights to bake correctly.
Hope it helps!
