Can a warp shader displace a cloud layer in the y axis (the input there of :) ) ??
I'm trying to make smoke .... yeah I know :)
I've stretched a very small scale cloud "density Fractal" in the y axis to make a uniform distribution and plugged that into a warp shader. The warper is a PF at a similar small scale with various displacements (I've tried).
I keep trying different settings but get no results, any suggestions?

Yes. Most displacement shaders default to displacement along the normal, and when applied to warping cloud textures this is the "up" vector pointing away from the centre of the planet. It's easier to do this than warping in the other directions, where you need a Redirect Shader.
Here's an example warping in X,Y,Z, but you don't need the Redirect Shader if you're only warping along the up vector:

cheers Matt, I;ll look in to it :)

Got to say, it works very well, and is a good starting point to generate a 'meta-cloud'.
