Ya, the problem resides with packer ignoring and not recognize some macro definitions and pass all in the headers, has VXGI- GFSDK_VXGI_x86.dll, not available in the dir, the linkage produce error’s later.
In the UE4 Editor logs, warnings and messages popup about missing and truncated things about unrecognized pre def macros also.
Commenting all files with VXGI (PublicDependencyModuleNames.Add(“VXGI”) - /|| (Target.Platform == UnrealTargetPlatform.Win32)/ and removing linkage for x86 libs, fix some things.
