Railroad Material
Browsing Artstation looking at displacement based materials got me inspired to try my hand at making one of my own - this is the result. This material was created entirely in substance designer, with the preview mesh quickly made in Blender.
All images were taken from the sketchfab viewer, using the exported heightmap as a displacement map. While the displacement effect in sketchfab was not particularly aesthetic, the actual material I think came out extremely well.

Material applied onto a tiled straight mesh.
Material applied on a curved mesh (same mesh as before but deformed).

Main frames in the substance graph pointed towards the elements they contribute to in the final material. Gravel was created using an existing material in Designer.
