Any ideas on doing this

If i remember right you used that method in your images Ulco?

To be honest; it puzzles me as well. Why doesn't the painted shader mask a cloud? It does a tiny bit, but maybe the area that's not painted isn't completely black. Though a color adjust doesn't help either. Strange.
By the way, you won't need the distri shader.

Yeah I found that out by removing it...got it to work but it looks all fakey. I think that except at greater speed than my craft would be making, all that foam is unnecessary. I think I'm going to just fo with a wake.

I rarely use the painted shader, prefer PS painted masks.

I rarely use the painted shader, prefer PS painted masks.

Me too. Much more control and easy.

I don't use the painted shader often,too,but if I remember correct you can paint
in the b/w preview of the cloud fractal directly.
Worth a try maybe.

Lately I as well use it less and, if you recall this started with  A SS shader as well not working.

SS shader not working for masking cloud, is that so? We have to check, as it should!

[j meyer]

SSShader works! Either connected to the PF direct or connected to the child layer input
of the distribution shader.
Btw you had connected the painted shader to the break up input instead of
the child layer input,so errrh ......

yeah re: SS shader...dunnow where my head was yesterday, got the SS shader working as expected today. Heh heh, hadn't noticed that Jochen, I never hook up in the nodes(that sounds dirty) and was certain I'd hooked it by the mask input so I dunno how that happened. Just making abstract graphics this A M with the Merge shader to fix in my mind what all the features do.
