Hi @Rohji,
The effect in your video suggests to me that your map might contain standalone lighting actor types (ex. SkyLight) where only a single instance of that lighting component can be active at any given time. Bear in mind that the TODM has these components (SkyLight, DirectionalLight, ExponentialHeightFog, SkyAtmosphere) as well. When multiple lights of these types are present, the behavior is arbitrary as to which actor will become active.
My guess is that you might have an extra SkyLight in your map. Could you confirm if you have any standalone lighting actors in your map?
