Oh, and also, I have a metrocop model but the model's hands aren't showing up, just Gordon Freeman's HEV Suit hands but blue.
There's only HEV, Citizen, Counter Strike, Day of Defeat, and Zombie currently, people are free to make their own however
The arms give what ever is the closest, which is why the HL2 Rebel player models give the standard Citizen outfit, it'd be difficult to make a mega ton of view model hands fit for every default player model
