Hi guys! I'm creating a cave scene where I want my 2D point lights to provide most of the illumination, but I can't seem to get my scene to darken. I'm using the URP template in 2019.4.1 and even when I change the ambient color in the lighting settings to black, it doesn't change the lighting in my scene at all. It's a 2D game and there are no lights in the scene except a single point light to test.
