I am wondering if there are links for Caustic project that shown in internet. I would like to have their actual UE projects, not EXE. So that I can play with it.
I just found them…In case you also would like to have a look those impressive demos in Unreal Engine itself, here is their link shared by NVIDIA.
For each NvRTX Caustics branch release version, you need to carefully read the readme docs from git page: https://github.com/NvRTX/UnrealEngine/tree/NvRTX_Caustics-5.2
You can find the corresponding downable demo projects link in that page as well, additionally, please copy and paste the BP_RTX folder from the demo project to your own since there is a couple of performance and quality trade off graphics preset I made for better scalability purpose for each platforms.
