SSE body/neck seam without textures

[shadowfox999]

To make it totally clear- 2 models (head, body) with all maps (diffuse,normal,specular) set to fully white 4096x4096 texture.

I don't know whats going on. It looks like shader issue but have no idea what can be wrong, lower nifscope shader data, strange head look is just nifskope interpretation. Any ideas how to fix that? I can upload more data from nifskope, just post what data may be important.

 

Edit: I reinstall SE, totally cleared skyrim se data and after reinstall the problem still exist, how can it be?
