Source Filmmaker

Source Filmmaker, abbreviated as SFM, is a video animation tool that utilizes the Source game engine system to create 3D motion shorts. It was originally made by Valve Corporation to make several animated trailers for Source games like Team Fortress 2 and Half-Life 2, but was released on Steam in 2012 for free use.

While most of the videos made from SFM feature elements from Team Fortress 2, numerous pony videos has been made with the engine as well, enough to make it it's own video category on Equestria Daily. This is done using 3D models of ponies and other FiM elements uploaded to the system. SFM currently includes models of almost every pony from the show, including non-pony characters like Discord and Gilda, fan-made characters such as Nyx, Snowdrop and Littlepip from Fallout: Equestria and maps of Ponyville and Canterlot.

Due to Team Fortress being the main core of the engine, the characters and elements from the game often carries over into pony videos. It's also one of the main arenas for Team Fortress and My Little Pony crossovers, and even include pony models dressed as the classes of TF2.

The website ponysfm.com serves as a general hub for models and other pony elements for the engine.
