Valve Index - Can you trigger the pass-through camera in-game

Is it possible to toggle the pass-through camera in-game from a blueprint without relying on double pressing the system button on the controller? I’ve done some digging and haven’t found any leads yet, so I thought I would check here.


Unfortunately that feature doesn’t seem to be available even in the OpenVR API itself. To my knowledge, the only way to enable passthrough from in-game is to get the camera image frames and project them to the players view, but that doesn’t give you access to the fancy real-time photogrammetry reconstructed view. There isn’t any available solution for this either, Blueprint or otherwise.
