At 1:19 Andrew says that rotations are not taken into account (I guess he is referring to pitch and roll, yaw should still matter), so my guess is that you would have to modify the code of the PanoCamera BP to make it work with rotations. Not sure though if this will even be possible due to the special technique that is being used to capture the 4 images and stitch them back together into a panoramic view.
