This is my entry into the Materialize Substance Designer contest. It is based on an image of a 3D printed shoe on Mattershots. The tweakable parameters include basic material tweaks (base colour, normal intensity, roughness, translucency) and a slider for changing the transition line between the two patterns. I didn't get as much time on this as I'd hoped and Iray isn't very stable on my Mac, so I opted to do fake translucency using an emissive map. I might re-visit this material and see if I can figure out how to do more physically accurate translucency in an MDL.
