Okay so I'm just gonna write up a quick tutorial so people who would like to have other helmets or body parts can add them without me having to change it for everyone due to varying tastes and preferences. Once CA release a variantmesh editor this will be so much easier but for now this is it. For this example I'll be adding a reiksguard head.

First off, we need to download the pack file manager from here[sourceforge.net]; this will let us edit pack files.
