    I am baking a tile normal map from blender. The end result looks like this:


    When I assign it as the Normal Map of an HDRP Lit material, I get this:


    Notice the weird grid-like artifacts that become very visible where there's specular reflection. I get the same results with the built-in renderer, and same results when I tried baking them again with xNormal

    Any idea what could cause this?

    Did you properly UV unwrap the tile before baking?

    Turning up the contrast on your normal map, this is what it looks like. Your bake is off. Most likely due to auto smoothed normals on your tiles.
