UE4 material study & Process

An old 3D asset from Helium Rain, retextured with a smart shader. I use vertex color to select different materials instead of manually painting textures. Materials are made of a "surface" function (flat metal, rough metal) and a "reference" probe (copper, steel etc), enabling easy composition of many different surfaces. Some tools enable procedural effects, like automatic edges :)
