Simulate VR HMD controller?

Hello, How can i simulate the rotation of the head of a VR headset using keyboard and mouse in the VR Demo project blueprints?
I think it should be a change into the MotionControllerPawn, HMDLocomotionPawn ,right?

I would like to know this too. How do I rotate the camera like if it’s a headset in the editor? Mapping the mouse to use the camera like in a FPS game doesn’t work because it’s connected to the pawn.
I have a 3D widget locked to the pawn, not the camera and I can’t test it in the editor because I need to rotate the pawn to rotate the camera or rotate the camera will rotate the pawn too.
It works on device but having to package the game each time is not very nice.
