In this short tutorial we'll show how you can make use of the Solid Noise and SuperNova filters to start you on your way to a cloud filled, star lit night. Start with a black background for a night scene. Add a black layer on top of that.
Lets clear out a little of the excess.
Add a white layer mask to the cloud layer. Now click back on the layer mask and paste the copied region into it. This leaves some clouds, but not quite enough. Small blotches of puffy clouds. But I like the smaller, more numerous clouds better.
