How to create white volumetric clouds in a dark scene? I am trying to create a scene which has a black background and the only ways to create volumetric clouds that i've seen results in ones which look believeable in light scenes but in dark ones they completely disappear. Anyone have any ideas?
First of all clouds can't be seen in total black night. We can see them only when moon shine a bit. So it's pretty accurate result.

But if you need you could just mix your material with emission shader.
