Build Enlighten UE4

To build the Enlighten UE4 editor:

  1. Install an unmodified copy of a supported version of UE4. This must be the major release, not a hotfix.
  2. Download the Enlighten packages compatible with your UE4 version.
  3. Extract the Enlighten packages on top of your unmodified copy of UE4, 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. UE4 Development Editor Win64

To evaluate Enlighten with a hotfix release of UE4 you can perform a three way merge between:

  • Left: your UE4 source tree with the hotfix
  • Right: the base UE4 + Enlighten source tree.
  • Common Ancestor: the unmodified copy of UE4.
