Maybe if you rotate it and add?

If the Alpine shader is 2d, does that mean that it is basically useless for 3D clouds? That would be a pity, because the Alpine shader does exactly what you see on the edges of some clouds.
It will project the same shape through it's altitude, so you could warp it with a 3d PF.

Some good experiments you've got going.

I think apline shapes are a good look too. I'm playing around with using the alpine shader as a vector warper for voronoi ridges noise and it seems it might be going somewhere.

WAS

Here is a quick test using the alpine as a warper, and depth modulator (inverted) to basic voronoi noise (0.5 contrast). It looks good to me, much better than what I was doing before which I kept wonder what "looked the best". The sinking of the denser ice crystals, and wisps of drafts pulling them out and up look realistic to my eyes.

I made a few more with different settings for the Alpine shader: scale step 6, stretch factor 7, and a lot of merging and warping.

I think these ones look really good! Great job Rene!

these are fantastic, great job!

Fine feathered cirrus, I like them! Good work.

They looks realyl great Rene, bravo! Will you mind sharing one example maybe please?

René

Here you go. The basic principle is quite straight forward. Subsequently I combined the alpine fractal with other fractals through masking and using the merge shader. With the latter a lot is possible by the way. And warping of course.

Thanks for sharing, René!

Thanks Rene. Much appreciated
