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!

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"

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

great HSL

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.

Nice!

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....
