Source Filmmaker(SFM) is a powerful, free animation tool created by Valve. It allows creators of 3D animated films to use game assets from Source Engine games. This guide will take you from installation to rendering to create stunning animations.
What is Source Filmmaker?
Source Filmmaker is Valve’s proprietary tool for creating animated movies with the Source engine. SFM is used in the cinematic trailers for Team Fortress 2, Dota 2, or Left 4 Dead.
SFM is based on the real-time rendering game engine, which means that what you see in your viewport will be what you receive in the final output. This makes it more efficient than traditional rendering pipelines.

- Three-point lighting setup: Use fill, key, and rim light for cinematic scenes.
- Create dynamic effects by manually keyframing or using the graph editor.
- Use IK Rigs: Easier posing for limbs — available for most Valve characters.
- Export image sequence for better quality: Use the PNG sequence, and compile it later.
