As you can see, the surroundings are night time but the edges have weird lights in them. I don’t know what to change in the Lighting properties. I want them to be realistic so no weird lights on the edges.
Did you try having it not quite 0,0,0?
Try 10,10,10 to see what that does. If not just click the box on the OutdoorAmbient and use the slider scale on the RH side until it looks good to you.
