We’ve been running into this issue quite a few times. Sometimes it goes away after deleting the matinee actor (and actors that it uses) and recreating the actors. The issue here is that when this specific matinee is triggered in-game, there will be some point during the timeline where the camera simply stops animating. The rest of the matinee plays on under the hood (i.e., the letterboxing is still active throughout the duration, then it stops normally, even firing off the Finished event to the controller). We see no reason for this to be happening - there are no events or even keys during the frame(s) where it stops (and it stops consistently at the same point), and there are no noticeable problems when previewing the matinee.
As I said, sometimes recreating the entire setup “fixes” it. But for this particular case that has us stuck, it stubbornly will not work no matter what we do. The camera actor is setup as a child of another, who has a joint animated in Maya that the camera is attached to. This same setup has worked for us in previous matinees.
Any ideas? Thanks.
