I already answered your question. You shouldn’t show both movie and background at the same time.
- If you already have shown background image then you could stop Movie is shown by manually set the movie index to an empty index in Movie Path.
- When you want to show movie on a certain level, set the movie index to your movie index and set the background index to an empty image in Background array.
This way you can control when and what you want to show in the loading screen. Hope it helps
