Adding an extra bit to a character/animal?

[Acornus]

Yeah, so not sure how to say this, but I'm trying to add some extra bits and pieces to certains assets in the game (maybe a penis to an animal, or something like that, but attaching a new piece of model to a previous model).

 

What is the best way to do this? Do I add it via NifSkope (I'm not sure what the method is call for this one, so if anyone has an idea, that would be grand, since I'm not too sure even by the wiki) or do I have to import the mesh into something like Max and, attach the bit/piece to the base model and re-export? Would appreciate some info.

Create a new Armor.

Find a valid body slot, and forget to alter the vanilla shapes if you want compatibility.
