Hmm GameSparks is a very common solution though that I imagine a lot of people use.
How about Oculus are you counting that as something that you officially support? As it is shipped by default with Unreal.
Because I get an error with that too as you can see in the log above,
UATHelper: Packaging (Windows (64-bit)): D:\software_installs\UE4\Epic Games\UE_4.18\Engine\Plugins\Runtime\Oculus\OculusVR\Source\OculusHMD\Public\OculusBoundaryComponent.h(4): fatal error C1083: Cannot open include file: 'ActorComponent.h': No such file or directory
There must be a way to tell the nativization process to look for these files?
