Normal map seam problem + artefacts in xnormal

I didn't have the time to look further into it.

I don't think it's a baking issue, i 've discovered that the resource compiler from version 3.5.8 is bugged and shows seams on the normal maps on the uv seams, there is a workaround by replacing the resource compiler with the working 3.5.7 version.

If this doesn't fix it, I should try to get my hands on cryteks xnormal tangent basic calculator plugin together with the supported version of xnormal which isn't available on the website anymore.
