Multiple CGI mistakes
Cameron clearly had to rely on some computer-generated imagery (CGI) for some of the more intricate scenes in the film, even though he wanted to use as many real effects as possible. This led to a wide range of issues, such as unrealistic-looking shadows, things that appear and vanish from the ship’s deck, and pipes that alter shape throughout the film.
That they weren’t left on the floor of the editing room is still a problem, but that is the risk associated with employing computer-generated imagery in movies, particularly in the 1990s.
