What is SFM (Source Filmmaker)?

SFM or Source Filmmaker is a 3D animation tool originally developed by Valve for creating Team Fortress 2 cinematics. The hentai community adopted SFM to create adult animations using video game character models. SFM hentai typically features characters from Overwatch, Fortnite, Resident Evil, and other popular games. While many creators have migrated to Blender for better quality, SFM content remains abundant online.
