To get started, please install from the following link:
You will need to have Steam VR installed to run with the HTC VIve.
Windows Mixed Reality will need to have Windows plugin for SteamVR to run with meetingRoom.
When you have installed meetingRoom be sure to click VR
Make sure to have your earphones and mic going to Vive rather than other speakers before you hit run.
Be sure to have both controllers turned on BEFORE starting meetingRoom.io - it will cause your avatar to not be able to teleport
