Still learning SD 5 so I picked up a Cobblestone material from Dishonored 2. What and amazing software. Based on the art of Yannick Gombart who recently had a dedicated article on 80lvl (where you can also find the reference I followed).

Will change/fix any issues I find or based on feedback. Hope you like it !
