Hey we have created our own VR template for the vive fully in C++. The only issue is making multiplayer work. Closest we have got is that the server replicates on all the clients but not the otherway. Anyone having similar issues or willing to share their own solutions to multiplayer in VR?
I believe there are several multiplayer templates around, the crux of it though you make each pawn update their head & hand locations if (IsLocallyControlled) and send that info up to the server with an RPC, then your server will update all the players locations on the clients.
For the manual replication go here, project files for Steam VR Multiplayer done live by Wes.
