Build Enlighten UE5

To build the Enlighten UE5 editor:

  1. Install an unmodified copy of a supported version of Unreal Engine. This must be the major release, not a hotfix.
  2. Download the Enlighten packages compatible with your Unreal Engine version.
  3. Extract the Enlighten packages on top of your unmodified copy of Unreal Engine, overwriting files where necessary.
  4. Delete the Engine/Intermediate folder, if it exists.
  5. Run GenerateProjectFiles.bat.
  6. Rebuild at least the following projects:
    1. UnrealFrontend Development Win64
    2. UnrealLightmass Development Win64
    3. ShaderCompileWorker Development Win64
    4. UE5 Development Editor Win64

To evaluate Enlighten with a hotfix release of Unreal Engine you can perform a three way merge between:

  • Left: your Unreal Engine source tree with the hotfix
  • Right: the base Unreal Engine + Enlighten source tree.
  • Common Ancestor: the unmodified copy of Unreal Engine.
