As with the Principled BSDF Wear Material this node makes use of a compilation of different procedural wear shading techniques wrapped up into a single easy to use node. The idea is to generate realistic and consistent wear effect on the surfaces of the material by masking different layers of shaders, extending the functionality of the Principled BSDF Wear Material to a wider variety of shaders and thus, material combinations, giving of the possibility of creating even multilayered materials.

This mixer node encompasses the next settings:

• Edge Wear: Level of wear calculation on edges.

• Scratches: Quantity and depth of scratches.

• Noise Scale: Scale of noise used to calculate the effects.

• Displacement: Level of displacement of scratches and mask borders.

A multi layered example material is included with its interconnected shading web.

This Shader makes use of the Bevel and Pointiness Input Nodes, which by the time being,are only processed in Cycles Engine. For this reason, only scratches are visible in Eevee. If devs make this two nodes processable in Eevee the shader would just work out of the box.

Just add the blender file to your asset library path, or directly append the material into your project.
