Normal-map issue only ingame (Blender model

Akaize

Ok, this is the situation. This is a third version of a set that I've abandoned, only the head, the rest are the second.

In Blender, Ok, no edges in the normal's division, no bugs..... (The textures are just for test)

In Game for some reason that problem occurred.

I already recalculated normals, and I tried some other things, but can't find the answer alone.

Can you help me guys?
