A while back I started exploring more hand authored looks in Substance Designer, this presents a difficult challange, as it's hard to replicate hand authored textures in a procedural way. I ended up sculpting some small bits, and baking out the height maps in Designer, just so I didn't have a billion nodes for a specific shape I wanted. I'm pleased with the result, it could use some more painterly effects overall, maybe softer edges in some areas, but I'm happy with it.
