Source Manager for Unreal Engine v1.1.0
Download SourceManagerSetup.exe below - per-user install, no admin rights needed, Windows 10/11 x64.
Epic Games Launcher engines are now supported
You no longer need a source build to use Source Manager. The app detects every Unreal Engine on your PC - precompiled Epic Games Launcher installs and GitHub source trees alike - and lets you pick the one it works against.
Auto-discovery (Get Source tab)
- Scans the launcher's own
LauncherInstalled.dat, theEpicGames\Unreal Engineregistry keys, the list of registered source builds, and the usual install folders - Every candidate is verified on disk, so engines you uninstalled long ago no longer show up
- Each entry shows its version, kind and path;
Rescanpicks up newly installed versions - On first run the app adopts the best engine it finds instead of pointing at a folder that is not an engine
Engine-compilation actions are hidden for precompiled engines
A launcher build ships no engine source, so there is nothing to clone, set up or compile. When one is selected:
- Sync & Launch drops the "Build engine target" step and renumbers the rest
- The Build tab hides the engine target picker, the Build button and Open UE5.sln, keeping the dedicated-server section
- Get Source hides the GitHub repository card and the Clone / Setup.bat / Generate project files actions
- Sanity check drops the Setup.bat and engine-build Visual Studio rows, and reports missing binaries as something to verify in the Epic Games Launcher rather than something to build
Everything project-side keeps working - Perforce sync, full project recompile, dedicated-server builds and launching the editor all run against a precompiled engine. Project files are generated through UnrealBuildTool for these engines, since they ship no GenerateProjectFiles.bat.
The Guide tab explains both engine kinds and when to pick which.
