I don’t know how new you are to Episode, but it’s quite simple. You won’t need more than two overlays.
- First, choose a background.
- Second, use an ambulance overlay with open back doors.
- Next, use a stretcher overlay.
If you put the ambulance overlay on layer 4, the stretcher on layer 2, and the character on layer 3, you’ll be able to put your character on the stretcher, animate the overlay rolling into the back of the ambulance, and animate the character moving along with it.
Please tell me if this makes any sense to you, if not, I can help you further. I’ve recently created a post just for things like this! Take a look, and you can get your scene fully coded!
