Are you sure that is the material assigned to that surface? It looks like the surface in the rendering has a Reflectance 0 map, but the material in your screenshot only has Roughness and Bump maps. If you want to email me the file, I can take a look.

The problem is that you changed the Tile X/Y for the Rougness map, but the Bump map Tile X/Y is still 1.0. Also, the Bump value of 40.0 is really high.
