But been looking on how to do that and its a bit confusing, do I set them up using nifscope, then sse nif optimizer?

 

Been trying to figure this one out for awhile and any help will be appreciated.

Okay good to know, now I have a npc I can replace the geometry data, do I have to do any editing to make them fit with eachother?
