Team Fortress 2 used to be about guns. Now it's all about hats. Fancy, ridiculous, elaborate hats. Ever wonder how those hats are made?
Let Bay Raitt, formerly of WETA (he's responsible for Gollum's face in Lord of the Rings) but currently of Valve Software, explain.
In this step-by-step guide he shows people how a professional Team Fortress 2 hat goes from the drawing board to the game in just three easy steps. Well, OK, it's more than three. And they don't look easy at all.
Still, if you're into this kind of stuff, it's an interesting read, especially towards the end where Raitt starts talking about the game's improved item submission process.
