[LE] Can't put together an NPC replacer?

[JoIt1]

Brand new to using CK and I am trying to make a simple NPC replacer for 1 person (with some modded assets). I have the mod needed and everything loaded in the CK but when I try to import the character gen parts this comes up, the face is fine but the hair and eyebrows (which are the modded parts) don't apply. I've tried looking it up and done like 20 different things but nothing has worked so far.

If you already have a facegen nif, you dont need the ck at all if exactly seeking to replace the look of one npc head. Thats all handled in the nif. The nif has strings. Strings in this case are labels of the editor ids for the face parts

 

You need only ensure the labels/strings of their face parts, match what the editor ids are in the ck. Even if you are using blue textures for eyes, if their eyes are called eyebrownfemalehuman or whatever its called in the ck, call them that in the nif too

 

Caveat is if you are using high poly on just this npc. Those have different tri files, so if using something special here with this npc you will need to setup a record in the ck pointing to that

 

This is much simpler than it likely sounds. Just a text matching text deal

I do not know what a nif file is, I'm very new to doing anything other than installing a mod lol. I am trying to make a replacer with a preset saved with the vanilla console from my character creation (made a .npc file).I'm not even sure if that is the right way to go about it but I saw it in a tutorial,

 

I would like to not use racemenu or a load of mods like a lot of methods suggest. If the nif is just another name for that .npc then how would I go about opening it, and if not is there a way to make a npc edit with it or should I try something else like an actual nif?
