Manny_S I checked out the sample scene and as I expected the 45 degree variant is more comfortable to watch than the 90 degree one.
I like the animation to improve UX explaining the viewer has to turn their head. On this topic, one thing I noticed in this sbvr video (https://www.sexlikereal.com/scenes/a-special-visitor-40250?t=2241) is that they chose to rotate the scene while keeping the "virtual" camera horizontal. I like this idea because it prevents the initial double vision and puts the onus on me to rotate the scene, which I am used to now anyway because of the experience with aligning a scene in PT.
