Issue w/ simple Substance Painter Normal Bake

Hi everyone,
I'm struggling with this seemingly simple normals bake. Along the seam I end up getting this weird normals difference. I'm have trouble finding a fix. Here are a few images to illustrate my issue.

That difference along the seam is totally reasonable, since your uv is somewhat rotated and isn't straightened either. Tangent space normal is like this. Does it cause a visible seam when its applied as a normal map? It shouldn't.

In other words, this is the expected behavior of a tangent space normal map.

Hey @Obscura, I imported into UE4 and everything is working fine. Before this bake, I was having an issue with the normal seams and a lighting issue. It looked extremely similar to this. I've got to figure out how to tell when it is properly baked
