Splitscreen sizing

I found info on the forum on how to do a splitscreen.
I’ve been using that to get different sizes for each screen, but unsucessfully.
For example, one screen about half the size of the other.
Can someone please show me how I can get this done?

You will just need to adjust the displayRegions and replace the values with the coordinates (0 to 1 I think) you want them to be on screen.

Thanks again pro-rsoft.
