More than a single shader, that's a tool. Say you have a simple, gray fbm as input (like the second example). What you can do is remap the darkest tones to a deep flat blue, the ones above to some other noise function colored in say brown, and you have a planet shader :) I use this tool to separate stones from mortar in Maya, from a single texture. See it here.

Awesome!

Post it in Material Database!
Check normals, dude!

Hi. Thanks a lot for all shaders you'v already made.
I want to ask you to create a shader to generate noise like procedural map in 3DSMax, but I have no 3DSM near to see what name that noise has.
AFAIR "Smoke noise" or "Turbulence" :oops:

What you describe sounds like it can be achieved using the built in fbm function.

great HSL :D
Is there a way to make it more like Lab in cylindric coords (HSL is basically just that for RGB) but with staying inside the limits of screen-colourspace? (I like the Luminosity not to make things white when it's at 100)

Ah, so you're wanting HSV? Actually, the HSL code I posted is buggy, and I have new, better RBG<->HSL functions (not on this computer though). Will post them when I get a chance.

Ah, HSV != HSL ?

I think I was expecting HSV too... I mean that's what I use with Maya :?

They're a little different.

I might write functions for HSV anyway.

Oh, yes :) there, 100 L doesn't mean white. That's better I think.... :)
