Supposedly developer version of HTC Vive is already available and some devs got it already. Does UE4 support HTC Vive already? If not, why not? 
There is a plugin in UE4 called ‘SteamVR’. I imagine this has something to do with the Vive.
I am actually going to EGS to start work on this stuff next month. As soon as I have docs up I will make a post with their location.
Cool! If only Valve would sell dev kits as OR does
great! hope UE4 will support Vive first
