There is no diffuse texture on this, the roughness parameter of the Metallic Paint material is being driven by a texture map, so you get a non-uniform roughness over the surface

There is also an Occlusion shader in the Specular channel, all done in the Graph Editor

Map driven roughness works just as expected, love it guys... would like to shake the hand or buy the guy who did this a pint or two ;)

At last!  "Old Metal Patina", like you see in museums.  I know which sandbox I'll be playing in after I get my darned client's project done!

Super!  Could you post the Graph?

Looking good Metal Master! I need to start exploring this Graph editor.

Is this close to having a real layered shader? I'm wanting to do something similar to the PBR workflow of, say, Substance Painter and Marmoset Toolbag.  Would love to have a base layer (metal) then a chipped/edge worn paint layer on top of that.

Also for the KeyShot guys - is it possible to do any edge detection in a material?  Would be great to be able to dial in edge wear 'N tear as a procedural.

Steve,

You can add a material with an opacity and bump map as a label to the root material. Technically this will act as a blended material rather than layered but definitely able to achieve your metal/paint example.

Edge detection? The curvature procedural does this.
