Source Filmmaker (SFM) is a powerful yet notoriously unstable 3D animation tool released by Valve in 2012. While originally intended for cinematic shorts within the Source Engine, it became the birthplace of a massive subculture of internet humor characterized by 'GMod-style' absurdity rendered with professional-grade lighting. SFM memes often feature Team Fortress 2 characters in overly dramatic, surreal, or nonsensical situations. The meme format itself often pokes fun at the software's steep learning curve, its tendency to crash, and the incredible contrast between the high effort required to animate and the absolute stupidity of the resulting viral shitpost.
