is there an option or a workaround to create a vertical swipe in an image sequence?
Its a bit of a janky hack, but have you tried rotating the container frame? I doubt this would actually work, but its worth a try.
You could then use the direct selection tool to select the content, and rotate it back.
unfortunately it didnt work. once you start the swipe the overlay rotates back and distorts into the size of the rotated frame. but it was worth a try. thanks!
You can try to make a scrollable frame and add the images to it... Might just work
