In 4.18 It seems there’s a bug where if I have two perspective viewports open and one set to Cinematic, when I hit play to watch my cinematic in the “Cinematic viewport”, when I move back to the default perspective it gets locked and I can’t move the camera like you normally can until I close and re-open the viewport. It’s also overlaying the Transport controls onto the default viewport for some reason. This is really frustrating as it means I can’t switch between the two viewports.
I’ll test it out in another project as soon as I get a chance to see if I can replicate it but I created this project from scratch with the sole purpose of learning sequencer so it’s completely fresh.
