Substance Study - Stylized Fan Cobblestones

More practice trying to get my procedural stuff closer to my sculpts. Tooling around with some new ways of building in these layers I would ordinarily approach with sculpting/masks in zbrush. Trying to get some cleaner, tighter results out with less spiky noise everywhere. ALSO!: resisting the urge to make everything as colorful as possible :S This one was fun!

(Also didn't like the way the base designer arc pavement node works so I tried coming up with my own solution that gave me more options)

Enjoy!
