The way it works is like this: There's a COBJ which defines the constructible object. There's a OMOD which defines an object mod. This defines a set of values that are changed, including material swaps and other data. There's a MSWP which an OMOD can point to, which defines material files that are swapped. You're looking in the wrong place. Unfortunately I don't think FalloutSnip or TES5Edit will be able to display nice editors for OMOD data. The Vault-Tec material OMOD simply has a modifier that says "shift the palette by 0.72, 0.72". It doesn't touch upon materials at all, because the palette is already part of the base Power Armor materials. If you want to do an actual material swap (to change the textures), you'd need to come up with an OMOD that does a pure material swap. You could try copying PA_Material_HotRod01 or PA_Material_HotRod02 or PA_Material_HotRod03 and edit what MSWP they point to (but be warned that they do other things -- like attribute bonuses, add name prefixes, etc). Then create your own MSWP form. http://imgur.com/faI02lW ^^ I believe this is what would need to be edited, but don't ask me exactly how as I'm not positive For the Military paint etc, it is actually defined in the MISC MOD section, has a listing for miscmod_pa_x01_material_military for instance, I believe you would change the MODT reference to your files, but Falloutsnip doesn't decipher it completely, so editing it right will be the trick to figure out
