Help with loading custom face texture

[firetruckboy2]

Hello, I am trying to make a companion mod. I am having troubles getting the custom head textures to load over the default ones.

 

I have tried everything I can think of off the top of my head, I edited the esp's texture set entry, I edited the head part entry to point to the right path, I edited the .nif file itself to point to the right texture. And nothing seems to work. Im not sure if I am missing something here, but it is quite frustrating.

 

Any help or insight is much appreciated so I can load custom face and back of head textures.

 

Thank you.
