Hi Guys, can anyone help with
having a crowd in the background or even just a few people doing their own thing in the back? whats the easiest way of coding this etc?

I would do it as spots and move them to layers while adding the animation. It isn’t easy but it looks nice.

Example;

@HOPE_EPISODE spot 1.234 567 890 in zone 1 AND HOPE_EPISODE moves to layer -1
