UE4 Multiplayer

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();

Save and build.

Edit config files in project.

YourProject/Build/Android

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.

why remove help mods?

Go to I had to recreate the post I made here because the mods removed it for reasons

https://www.reddit.com/r/unrealengine/comments/optd6y/the_secret_oculus_quest_2_multiplayer_guide/

I hope this helps 🙂

stupid mods deleted the fix and step to step guide I made sorry we live in a world of idiots

for **bleep** sakes

Mods just wasted 30 minutes of my **bleep**ing time
