how to make the VR camera move following by the path with the blueprint?
I have set the VR pawn with the scene and camera and a cube which will be used to make the interactive.
I tried to make the matinee to make the camera moving followed by the path. And I can use the VR Pawn to make the basic interactive. But I can’t combine the moving camera with the camera of the VR pawn.
The effect I need to reach is that I can move the VR pawn and make the interactive without the motion controller.

Anyone can give some suggestion?
