Tileable material made with Substance Designer 5.
It’s possible to plug your own height map to replace the skulls with other kind of bones/rocks etc.
This substance is very powerful, you can set the number of rocks, input, their colors, ground elevation, intensity of the cracks and more as you can see on the graph.
Except for the skulls, everything is procedural and done inside Substance Designer 5.
Skulls sculpted and baked in Zbrush.
