I'm working on a few compaions and i would like them to each have their own custom body and face.(Like people do for a custom race mod).I have the geck and nvedit.Can this be done and if so how,Any help would be great. China.

NosRhyfelwr wrote a decent tutorial demonstrating how to construct a companion using his NosCo Companion System (http://www.newvegasnexus.com/downloads/file.php?id=38059). In the advanced section of the tut, he tells you how to add custom bodies to the companion. Adding a custom face texture is similar.

Basically, in GECK, you create a new custom race for each npc, link in custom meshes and textures, and set the npc as that race.

I am curious, what companion system are you using?
