Export Mesh for BBW Races

[Sunspot2]

Hello, I'm trying to create a head for big women that fits vanilla and CB++.

The problem is, I cannot export the mesh into a usable nif.

Whenever i do it (more than 100 attempts), something goes wrong.

I followed many different blender import - export tutorials.

Can anybody please export the mesh making it usable in Skyrim?

Don't worry if the neck is too long and end up inside the body, that will be adjusted by femalehead.tri morphs that i successfully edited.
