Unreal Engine Blueprint API Reference > Input > Head Mounted Display
If the HMD has a positional sensor, this will return the game-world location of it, as well as the parameters for the bounding region of tracking. This allows an in-game representation of the legal positional tracking range. All values will be zeroed if the sensor is not available or the HMD does not support it.
