    Install and build

    Oct 10, 2019

    Enlighten SDK 3.09 is integrated with Unreal Engine 4.14.0 through 4.23.0.
    Enlighten UE4 is distributed as a collection of .zip files containing modifications to the base UE4 version.
    The distribution .zip files are named as follows:

    EnlightenUE4-[Version]-[UE4 Version]-[Type].zip

    Version is the version of Enlighten. This comprises:

    • the Enlighten version number
    • R denotes the initial release; Pn denotes patch n
    • the internal build number

    UE4 Version is the version of UE4 this package is compatible with

    Type may be:

    • Base — Required. This zip contains the modified engine files and the Enlighten libraries and tools.
    • Samples — This zip contains maps and assets demonstrating Enlighten, contained in EnlightenSamples.uproject.
    • Platform specific files — Extra files required to run on console platforms. These are provided only to registered platform developers.

    For example EnlightenUE4-3.09.R.12345-UE4.21.0-Base.zip contains the Base files for the initial release of Enlighten UE4 version 3.09 compatible with UE4 version 4.21.0.

    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.
