For this pattern, I modeled torus spirals in maya and layered them together before rendering a depth pass to import into substance designer. I used the depth pass to create color and opacity maps as well as colors in substance designer. The substance itself, allows you to change the color, selectivity, metal-ness, roughness, orientation and size of the bitmap. These properties are also reflected in the MDL. For sketchfab, the material is rebuilt with the PBR workflow material for Sketchfab.
