help with obsidian texture

[korbendalas]

Hello,

I'm trying to create an obsidian texture in COP using Fractal noise node that problem I'm facing is this node does not have an id output so I tried 
segment by value node but i didn't get the results i needed, I'm trying to get every chunk generated have its own textures values and orientations.
If there is a way to achieve this effect using Worley noise I'll be glad to use that node since it has it's own id output

Any idea or guidance will be much appreciated

 

Thank you
