The first is how to setup VR in the 3rd person Template (and to make it a first person one too) with a view that is separate from the controls. It also trys to explain some things that are often glossed over: ?v=YU3TEu_jT6Y
The second on is on setting up the performance and helpful settings for using VR on UE4: ?v=2Yc_Lz-uRdU
