Hello! The zoom viewport and parallax viewport can coexist in the same project with no issues, but their functionalities can't quite be combined - if you nest them then I believe one viewport is prioritized for the input. It's not a bad idea though, so I'll put that in my back pocket to potentially combine! I might need to adjust the behavior of the parallax so the zoom looks nice too, since it's currently designed just for one depth level. I will reply to this comment if I do make a combination one!
