Where Does Twinmotion Save Projects and Libraries?
Twinmotion saves .tm scenes where you choose, with UserLibrary in Documents and cached assets in Local AppData.
Last updated
Twinmotion projects (.tm) go where File then Save points. Everything reusable splits into two roots: UserLibrary in Documents for your own assets, and a persistent Library cache in Local AppData for Twinmotion, Megascans, and Sketchfab downloads plus templates. That split arrived with the 2026 library setup window.
Autosaves default to Documents Twinmotion version AutoBackups every 15 minutes keeping 3 copies. DirectLink textures land beside the version folder too. Point new installs at the same persistent Library path to avoid redownloading gigabytes of content.
Where Twinmotion stores this, by platform
C:\Users\[Username]\Documents\Twinmotion\UserLibrary
Autosaves in Documents\Twinmotion[version]\AutoBackups. Cloud cache in %LOCALAPPDATA%\Twinmotion\Library. Change roots in Preferences and Custom paths or Edit and Library transfer.
~/Documents/Twinmotion/UserLibrary
Same Documents layout with colon separated Finder paths. Cache under ~/Library/Caches/com.epicgames.TwinmotionCookedEditor. Path Tracer features remain Windows only.
Frequently asked questions
How do I stop Twinmotion redownloading the library?
Keep the persistent Library path stable across versions and accept the setup window default. Copy the AppData Library tree and Documents UserLibrary together when moving drives.
Where are Twinmotion autosaves?
In Documents Twinmotion version AutoBackups by default. Adjust interval, count, and path in Preferences and Save. Projects saved in a newer version do not open in older builds.
