Note: These versions can have a lot of bugs :)
Inside the Release SourceCode.zip files are shaders and pieces of code that are supposed to replace vannila code

DeferredShadingRenderer.h

• Overwrite RenderRayTracingPrimaryRaysView() Function Declaration at line 1083

RayTracingDebug.cpp

RayTracingPrimaryRays.cpp

• Overwrite the Whole file

Shaders

• Add all shaders into Engine/Shaders/Private/RayTracing

Launching Old Sample Projects

• If Unreal Engine complains about Project Version, Select "Convert in place"
  
• When Loaded, load the emptytestmap level
  
• After that select the AquarayController Actor and in the Properties Panel click the "Enable AquaRay" Button to start the Renderer (and hope it doesnt blow up)
