>>2164371source filmmaker, the program used by valve to make the "meet the team" videos and other team fortress 2 shorts (expiration date, etc). it was probably used to make the l4d/l4d2 trailers too but i'm not sure.
it's now easily accessible to the public, and as such, people immediately made porn in it. i've used it myself and can definitely say that it's much better than trying to animate in garry's mod, as it's actually made for animation
