Source Filmmaker for Windows

The Source Filmmaker is a digital production software that operates within Valve’s Source game engine. It combines asset-based editing, animation control, and rendering into one environment. Using in-game materials such as models, textures, and effects enables direct construction of animated films and still images for games like Team Fortress 2. 

The Source Filmmaker system features three primary editing modes, Clip Editor, Motion Editor, and Graph Editor, each handling different aspects of sequence and animation control. By merging asset management, camera placement, lighting configuration, and sound alignment, SFM provides a what-you-see-is-what-you-get platform where the final output reflects the real-time editing viewport.

Creative toolkit for better and efficient workflow

Source Filmmaker incorporates three editing modules that form the structure of its workflow. The Clip Editor organizes video and audio clips into sequences, allowing placement and timing adjustments across multiple tracks. The Motion Editor controls model poses, movement, and transitions, enabling complex character animation with adjustable timelines. The Graph Editor provides fine-grained editing of curves and keyframes, giving precision over motion paths, pacing, and blending between poses. 

Lighting and camera functions are embedded directly in the same interface. You can position virtual lights, adjust intensity, and modify shadows in real time using the Source engine renderer. Camera tools allow multiple perspectives with keyframed paths, focus depth, and lens effects. These features are not handled separately but integrated within the same viewport, ensuring that edits to movement, lighting, or framing are all visible within the projected final output.

It provides a library of built-in assets drawn from Valve titles such as Team Fortress 2, along with models from official shorts. Additional content can be imported and treated as native to the environment. Beyond asset integration, it links to official documentation, FAQs, and community resources for reference and troubleshooting. Bug reporting functions are also embedded, allowing developers to receive technical feedback. However, it's dependent on imported or bundled assets.

Discover the hassle-free and asset-based animation

Source Filmmaker merges asset-based animation, editing modules, and rendering tools into a single Source engine application. It includes three dedicated editors for clips, motion, and curves, alongside camera and lighting systems embedded within the same viewport. It includes integrated real-time rendering and centralized editing tools, while its limitations stem from dependence on Source engine formats. It’s structured as a full production tool for building animated films with in-engine content.
