How to make a patchy cloud layer?

Question

I want to make a cloud layer like shown in this image (where parts of it are empty patches).

I tried doing this by applying a volume scatter shader to a cube and then controlling the density with a have texture but it outputted as such :

I need this to look realistic, how do I achieve it? I tried applying the method of a tutorial by BlenderGuru, but could not get it to look patchy.

This is my setup:

Clouds in a volume cube are quite hard actually. May need particles and multiple volumes? — 3pointedit, Nov 22 '17 at 11:22

You have to put a color ramp in front of the multiply node to crush the noise node input into something workable with a color mix.

$\begingroup$ Im assuming you mean the VECTOR input. Vector is attached to the mapping node. if you have the node wrangler addon active, press CTRL+T while having a texture node selected, it auto-inserts them. This isnt anything thats necessary though since the procedural nodes automatically assume generated mapping anyways. I just did it out of habit. $\endgroup$
