I basically adjusted the armor parts from 3 and reach to the halo 4 body (and weighted them to it too) so I can basically use it as a resource for whatever I need, like for instance Skyrim which I have the armors adjusted to. I can do the same with fallout new vegas/3 if needs be as well
Only thing that needs work desperately is halo 4 armor's textures
Which 343i decided to for whatever reason pack the diffuse, specular, metalness, and color correct maps all into one texture
