UE 4.25 Sun and Sky Actor - too bright at night. How to control ambient light?

[presto423]

Even in the video from the previous, site, he used a light with just 12 lux, not 50000 or 75000. And i got that bad looking band too, after going beyond 50 lux.

I set the directional to 1 lux (low intensity moonlight), and had the sun band. It was when I tweaked the Sky Atmosphere settings that I found lowering Rayleigh Exponential Distribution removed the horizon band of the sun (directional light index 0, the SunSky-inherited directional light) at value 1. It would probably be higher or lower depending on the lux of the directional lights and at least a few other settings in Sky Atmosphere / skylight.
