I tried to port it myself yesterday but I think they changed up some things after adding forward shading in 4.14.
I get an error:
Failed to compile global shader FTiledDeferredLightingCS1 Line 986 in GlobalShader.cpp
Which is piece of code:
UE_LOG(LogShaders, Fatal, TEXT("Failed to compile global shader %s %s %s. Enable 'r.ShaderDevelopmentMode' in ConsoleVariables.ini for retries."),
GlobalShaderType->GetName(),
Pipeline ? TEXT("for pipeline") : TEXT(""),
Pipeline ? Pipeline->GetName() : TEXT(""));
