Looking for Attic scene files (Using Developer Caustics edition )


I previously had some project files which i have since lost. For this project- https://developer-blogs.nvidia.com/wp-content/uploads/2020/12/figure_15.jpg

They are from Unreal/Nvidia to make this Volumetric Light/God rays.

Does anybody know where i can re-download it?

It was on Nvidia Developer Caustics page but have checked all downloads and nothing…
