I’m joining this circle going in circles, was able to get Camera 2 to finally show up after trying the various ideas above, then placing cursor in the Timeline at start frame of Camera 2> click + Camera Cuts> selecting Camera 2> click greyed out camera by Camera Cuts to turn white> save - I was then able to see Camera 2 in MRQ, was able to render, but only that shot. I tried the same steps for Camera 3, but now getting nothing but “no shot…”. Documentation indicates all cameras/shots should appear in a list under the Cine_Level added to MRQ once those cameras have been added to Camera Cuts, but then what are the specific steps to get that list to appear, if not by first adding them to Camera Cuts and seeing each clip labelled correctly in the Camera Cuts Timeline? This can’t be that hard, can it?
Addendum. I was able to begin using Camera Cuts to switch between cameras assigned on the timeline by creating a new Level Sequence. These evidently can get corrupted. If you’re confident your Camera Cuts are properly assigned in the Timeline and in MRQ you add your Level Sequence, expand it to see what shots show up and see “no cam”, that’s probably a clue your Level Sequence got corrupted.
