Help: Why is My 2nd UVMap Showing on the Main UVMap?

Hey guys, so i was trying to import the batmobile from arkham knight game. but it lacked some textures like the Carbon Fiber pattern on the wheel arc.

So i watched some youtube tutorials about multiple uv maps.
and followed this:

The problem is, i think i didn’t quite follow it, and the result was a mess (i used a normal map image because the albedo is hard to see, but if i did it right, the violet image shouldn’t have been showing in all the mesh, but it should be showing on the fiber map since it is already defined in the Nodes.

here’s the result, can you please point out what i missed?

Oh i found it! Set the fibermap to Clip instead of Repeat.
