With the Blueprint now complete, we just need to add some objects to the world to pick up. Since the objects we are looking to pick up must have a physics body, you can just add a few Static Mesh and set their Mobility to Movable and also make sure to enable Simulate Physics.
Then place the VRPawn in the world and make sure to set Auto Possess Player to Player 1 and launch your project using the VR preview. Next, put on your Rift HMD and pick up your Touch controllers and aim the Left Touch Controller in front of an object you want to pick up and squeeze the trigger to pick it up. Release the trigger to drop the object and pick up another one like in the following video.
