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.
