I'm late in seeing this thread, but I've had this same problem. I don't have Vue 3 to try it out on, but it has done it to me in Vue 4, and I believe in Pro as well. I'm unclear why putting the camera within the set piece should do this. The only thing I could think of it and it does have it uses, would be it considers the camera to be underwater and makes everything that blue. That is very helpful, but not if you want to have a camera place within a large room without going for a tight zoom. Is there an option to shut this off? Anyone?
