So I’m trying to make a Virtual Production set, I’ve got a Vive Tracker connected to my camera and I want to virtual camera in Unreal to move along with my Vive tracker. I used the get tracked device position and orientation node and everything worked perfectly when i clicked on Simulate! Then i switched to a Standalone Game and it worked too. However now when i switched it back to Simulate it just refused to work! There was no information coming through tracked data. Some kind of link between Unreal and SteamVR seems to be broken. Can anyone help me as to why this happens and how I can fix it?
