FAQPage Schema
How do I launch Unreal Editor with a custom engine build automatically?▼

To launch Unreal Editor with a custom build, the tool auto-detects the `.uproject` file in your current directory and resolves the correct engine path from cached data or the Windows Registry.

How does engine path detection work when opening an Unreal Engine project?▼

Engine path detection works by reading the project's `.uproject` file and querying cached engine paths or the Windows Registry to locate the specific Unreal Engine installation directory.

Can I regenerate Visual Studio project files before launching Unreal Editor?▼

Yes, you can optionally regenerate Visual Studio or Rider project files using UnrealBuildTool before launching the Unreal Editor for your current project.

Does this Unreal Editor launch tool work on macOS or Linux?▼

No, this Unreal Editor launch tool is specifically designed for Windows environments and relies on the Windows Registry for engine path resolution and project file operations.

What's the best way to open a specific version of Unreal Engine from the command line?▼

The best way is using a launcher that dynamically resolves the engine path from your project's `.uproject` file, ensuring the correct custom engine build opens instantly without manual path configuration.

Why does my Unreal Engine project fail to find the correct custom engine build?▼

Finding the correct custom engine build fails if the `.uproject` file is missing from the working directory or if the engine installation path is not registered in the Windows Registry or cache.
