I’m getting a build error for the NvRTX 5.0.1-1 release:

4>Creating makefile for ShaderCompileWorker (no existing makefile)
4>UnrealBuildTool : error : Unhandled exception: Dependency file “C:\Users\User\Desktop\UnrealEngine-nvrtx-5.0.1-1\Engine\Intermediate\Build\Win64\UnrealHeaderTool\Development\Json\Module.Json.cpp.json” version (“1.2”) is not supported version
4>C:\Program Files\Microsoft Visual Studio\2022\Community\MSBuild\Microsoft\VC\v170\Microsoft.MakeFile.Targets(50,5): error MSB3073: The command “…\Build\BatchFiles\Rebuild.bat -Target=“UnrealEditor Win64 Development” -Target=“ShaderCompileWorker Win64 Development -Quiet” -WaitMutex -FromMsBuild” exited with code -1.
4>Done building project “UE5.vcxproj” – FAILED.
========== Rebuild All: 3 succeeded, 1 failed, 0 skipped ==========

Not sure if this is related to Nvidia or Unreal Engine source. Any ideas?

Cheers.

Hi @gatzkerob this has been fixed in 5.0.2. The Epic Launcher BINARY version has been fixed.
The was a source patch PR, but Epic officially fixed the patch to VIsual Studio Source in 5.0.2 as well
In Visual Studio 2022 select the Github window and click the down arrow “git pull” function to get the new source updates then Click Clean and Build to rebuild the patches
