Seam Issues

I’m notcing that the UV Channel 1 inside Unreal moves over to the right about half an inch, not sure if it’s supposed to do that or not?

EDIT -

Turns out it is my Normal map

Is there something special I need to do with the Normal map?
I mean if I disable it I can see see the seams, but it’s not from darkening, just from a seam in general.

So it has to do with the Normal Maps.
Does Unreal have something special I need to do with the normal maps?

I got it guys!

But now I’m running accross another issue, when I look at my character model Frame must drop dramatically because game will freeze for like 3 seconds then get really glitchy with model in view.

Has like 33K Polys.
