Build Enlighten UE4

To build the Enlighten UE4 editor:

Install an unmodified copy of a supported version of UE4. This must be the major release, not a hotfix.
Download the Enlighten packages compatible with your UE4 version.
Extract the Enlighten packages on top of your unmodified copy of UE4, overwriting files where necessary.
Delete the Engine/Intermediate folder, if it exists.
Run GenerateProjectFiles.bat.
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.
