Help, I don’t understand why the emmisive light makes such noise! how to configure NRD?
Hi there @cattemeo and welcome to the NVIDIA developer forums.
NRD is not a UE plugin, but there are many other things to look for that might help. For example enable TSR or some other AA feature, change the material reflection parameters of the material, check if you have ray.tracing enabled or not.
Are you using the DLSS plugin? If so then the built-in DLAA will address the noise to some extent. And many other possibilities.
I’ll try but I’m using the nvrtx version and there is an NRD plugin I don’t understand how to configure it
Well, if you don’t need it you don’t need to worry about it. Otherwise the github pages are the main source of information about this tool: GitHub - NVIDIAGameWorks/RayTracingDenoiser: NVIDIA Ray Tracing Denoiser
Assuming you are in Caustics branch or NVRTX 5.4 and have the DLSS & NRD Plugin enables you can toggle the denoiser mode on and off between Reblur and Relax using the following console variables:
Relax Mode:
r.NRD.Technique 0
r.NRD.Indirect.Technique 0
Reblur Mode:
r.NRD.Technique 0
r.NRD.Indirect.Technique 0
For DLSS Quality - set
r.screenpercentage 66.7
r.NGX.DLSS.Enable 1
Turning up Lumen Scene quality and number of samples on some other CVAR’s may also help to denoise the lights and shadows, but there are so many different variables it would be hard to know without experimenting what will work best for you here.
Check project settings that RTXDI is turned on, for the shadows, turning on ray reconstruction may help as well, for that I refer you to the documentation:
https://github.com/NvRTX/UnrealEngine/blob/nvrtx-5.4/Engine/Plugins/Runtime/Nvidia/DLSS/README.md
Guys, how the hack did you open the CausticsBranch?
Im really a newby to GitHub, i followed the video instructions on official NVidia, but when im trying to open the build from VS, it said “The system cannot find the UnrealEditor.exe“, also in my project foulder → \UnrealEngine-NvRTX_Caustics-5.4\Engine\Binaries\Win64 there is no UnrealEditor.exe
Does anybody know, please help
