Hi JokerJenkins,
If you want an entirely dark scene, you’ll need to do some of the following:
- World Setting > Lightmass > Environment Color > Change this to the default black.
- SkyLight > Set intensity to 0 or a very low value like 0.15
- If you rotate the sun to be below the landscape or the horizon line you’ll need to set it’s intensity to 0.
If you’re ultimately wanting to do a time of day kind of setup with fully dynamic lighting and no baked lighting you can check out this project here that I made using a users tutorial as a starting point: [TUTORIALS] Photons Be Free: Mini-tutorials and other curiosities - Community & Industry Discussion - Epic Developer Community Forums
I hope this helps.
Tim
