🎬 What is SFM Compile?
SFM Compile refers to the process of rendering or exporting your animation or video project in Source Filmmaker (SFM) into a usable video file, like .mp4 or .avi. It takes all the assets (models, lights, cameras, sounds) and compiles them into a final format.
SFM, developed by Valve, is a powerful free tool used by creators to make short films using assets from Valve games such as Team Fortress 2 and Half-Life.
