Yami Amagi Body Change

[Nintendude1236]

Hi there! So, I'm trying to give the custom follower Yami Amagi by guicool a UNP body. She doesn't have a UNP or CBBE body by default, just whatever guicool hooked her up with. I think I've figured out how to do it for the most part: Use the Archive.exe that comes with the creation kit to open her .bsa, then replace the body meshes in there with the desired UNP meshes. When I cracked open the body mesh folder, though, there seemed to be 7 files instead of the standard 6 (2 body, 2 hands, two feet)? What could this 7th be? Should I try and find a way to read these files somehow? Come to think of it, if her default body doesn't is nevernude, will I have to give her new textures too?

 

Any comments would be appreciated, just keep in mind I'm not really proficient with editing bodies and textures like this.
