Texture issue

Can anyone tell me why I'm seeing this join on my player's head? It is only apparent when zoomed out...

Zoomed out:


Zoomed in:


As you can see there shouldn't he a problem with the UV edit:


Is it a lighting problem?

looks like you didn't merge the vertices at the seam on the head so you have 2 seperate normals on that vertex which means 2 different lighting on both sides of the seam most likely.

but thats only a guess.

Hm, any idea how to fix that using Unwrap or FragMotion?
