I'm working on an Immersive game that requires Controller input. The Happy Beam sample is supposed to support hand tracking and controller input. I have tested the controller input with a PS5 Dual Sense controller and all I can do is move around the scene while the game plays. But cannot interact with anything in the scene. Can anyone confirm this and or suggest how I can use a controller in an immersive space? I cannot find a single working example.
