Using the Cloud Editor
If you have in-game fog visibility set to 100 for instance, there will be a sharp white-blue edge on the horizon where the cloud layer meets the sky.
If you instead set fog visibility in-game to about 20-22 miles you will no longer see the sharp edge at the horizon. The cloud layer will then look more natural.
Plus it's not pink like the 1-4 clouds created by the cloud editor ;-)
