Simple normal map causing weird seams

ntomassetti

I've been running into issues trying to get my texture to seamlessly repeat but the normal map is causing some weirdness on the edges.  It repeats vertically but horizontally I get weird lighting (shown below).  Is there something I need to do in the material with the normal map to make it know its a repeating texture?

the normal map is not clean. it seems to have a slight horizontal gradient which breaks the tiling.

Oh strange I guess I kind of see it now that you mention it.  I baked the normal map with xNormal so I guess I'll try it without.

It does not matter in which software you bake. Try to adjust normals if this just simple plane geometry. If you bake also check that your UV edges are parallel with texture edge.
