One of the first procedural shader for Cycles.
My goal - create extensive thematic smart shaders for quickly texturing without unwrapping.
This is first of CGR Shaders collection.
I think you over-processed the first image to the point it looks fake/cartoony. The actual shader on the arm model and the totem looks very, very good however!
Wow those shaders look awesome Vizuaris! I love the tarnished shaders and the one on the arm is amazing, I’ve never looked into creating a procedural shader before - what’s your process if you don’t mind me asking?
Exp. thanks Blender Guru & Creativeshrimp + analysing some surface references & many many nodes 
Very usefull Shift+Ctrl & click on the node. It allow prevew for what are you doing & of cause Renrered preview! For now, I think, Cycles has the most comfortable node building system.
That is great for procedural. It is nice to get out of the world of unwrapping and image texturing, because I think you can get more control potentially once you learn it… I mean I would think anyway. Anyway, beautiful…
