Figuring out TF2's war paints for GMod

[meharryp]

I've been trying to figure out how TF2s war paint system works to apply the all weapon skins to weapons in gmod.
Here's what I've got so far:
A war paint is a combination of multiple textures combined in to one texture. Somewhere in TF2 the texture combinations and offsets must be defined, so I started by looking for those
Skins that can be applied to a single weapon are stored in scripts/items/paintkits_master.txt, but this file doesn't contain the new war paints (seemingly)
items_game.txt also does not contain any information on war paints, but interestingly all war paints are named "Paintkit XXX" where XXX is a number
The Dragons Fury war paint is the only war paint has VMTs that define how it looks instead of paintkits_master or some other file that I've missed

Any help or information on how war paints work would be appreciated (and rewarded with a coin maybe)
