Fully procedural material inspired by the floor we can see in the concept "An Ear to the Wall" by Piotr Jabłoński made for Dishonored Death of the Outsider
I had a lot of fun on this one, I tried to add some interesting shapes and variations to fit the art direction I was aiming for.
100% Substance Designer
Rendered in Marmoset Toolbag
