I have a Meta Question 3S headset, how do I connect this to the latest version of TM?
I have already tried connecting via the eye (top right) but VR symbol is greyed out when the headset is connected via the cable.
Unreal engine requires SteamVR to also be running and connected to the headset (before you open your project) as it uses the steamVR API to launch VR Preview. Otherwise VR Preview will be greyed out like it is for you.
