How to Use Source Filmmaker: Step-by-Step Beginner’s Guide 2025

Source Filmmaker (SFM) is a powerful free animation tool developed by Valve that allows creators to make 3D animated films using game assets from Source Engine titles. This comprehensive guide will walk you through every step — from installation to final rendering — so you can begin creating stunning animations without needing to consult multiple sources.

Source Filmmaker (SFM) is Valve’s proprietary tool used to create animated movies using the Source game engine. If you’ve ever watched a cinematic trailer for Team Fortress 2, Dota 2, or Left 4 Dead, you’ve already seen SFM in action.

SFM uses the game engine’s real-time rendering, meaning what you see in the viewport is what you get in the final output — making it efficient and faster than traditional rendering pipelines.

Once you open SFM, you’ll see a workspace divided into the following key panels:
