When I try to load the VirtualRealityBP MotionControllerMap, The “VR Preview” button is greyed out – I can’t test the scene on my HTC Vive.
VR Preview is also greyed out when I try to run using Unreal’s official set-up guide (https://docs.unrealengine.com/latest/INT/Platforms/SteamVR/QuickStart/2/index.html)
Any thoughts on how to fix this?
Running Unreal 4.15.0 on Ubuntu 16.10, Nvidia 375.27.10 (Vulkan build) proprietary drivers, SteamVR beta and Steam client beta for Linux, Unity 7.5.0 desktop environment, Xorg 1.18.4.
I added a post in the Steam forums, too (http://steamcommunity.com/app/250820/discussions/5/133258593397992746/?tscn=1488704512).
