Hello there is no step to step guide sadly and the process is a pain in the ass but I got it working. First you will need to use Oculus source 4.26.3 and you will need to fix some code errors that prevent travel to the host headset from the client headset. But I will do my best to help you out so you don't waste months on this as I did.


Plugins/Online/OnlineSubsystemOculus/Source/Private

IPAddressOculus.h
Line 184

 

FString ToString(bool bAppendPort) const override
{
return FString::Printf(TEXT("%s.oculus"), *OculusId.ToString());
}

 

OculusNetDriver.cpp
Line 290

 

void UOculusNetDriver::LowLevelSend(TSharedPtr<const FInternetAddr> Address, void* Data, int32 CountBits, FOutPacketTraits& Traits)
{
if (bIsPassthrough)
{
return UIpNetDriver::LowLevelSend(Address, Data, CountBits, Traits);
}
//const FInternetAddr* AddressPtr = Address.Get();
//const FInternetAddrOculus* OculusAddr = StaticCast<const FInternetAddrOculus*>(AddressPtr);
//check(OculusAddr != nullptr);

FInternetAddrOculus OculusAddr(FURL(nullptr, *Address->ToString(false), ETravelType::TRAVEL_Absolute));
ovrID PeerID = OculusAddr.GetID();

Make sure you have your ExampleKey.keystore file in your Android folder in project.

*Optional after first build you can make a ManifestRequirementsOverride.txt in same location to make sure permissions are setup right don't worry about this now you will need to have a generated manifest for this in your intermediate folder.
