What is the difference between Add to viewport and add to player screen?

Add to Player Screen is mainly used for split-screen games where you only want to apply the UI over a specific players screen.

This is valuable in a split screen game where you need to only show a widget over a player’s portion of the viewport.
Add To Player Screen


That doesn t seem to be working. I have split my screens into two and use the add to player screen and still it doesnt add it to anything but theoverall screen. Any tutorials on this? Thanks!
