custom follower head for a custom race

[florent303]

Hi,

 

I found a follower that's i want to make a custom race playable. But when i excart the .bsa file where is no head meshes, eyes, mouth, ... only body, feet, hand and a chargen .nif and a lot of .tri. It's possible to make a head part form this .nif ? and if Yes, how ? I try to excart head part with blender but they don't show ingame.
