Create a simple scene
Add a Skylight and set the standard daylight cubemap that comes with the engine
Now make the skylight invisible with the eye-icon in the world outliner
Result: The skylight will still influence the world as before. The light has to be disabled with the “affects world” checkmark instead
Expected: The Eye-icon should deactivate the skylight in the editor like any other light. This makes applying different baked lights in multiple levels easier
