I think I see what you mean but I’m not sure… Are you talking about when the character fades out, like he’s disappearing or when the character just go to another side while zooming so we can see the character that are behind them?
If you want the character to disappear (like a transition) you’ll have to use the background as an overlay…
If you want the characters to move you’ll need to make them walk while doing an action that isn’t a walking action (idk if that make sense.) If you need more precisions, feel free to PM me!
