OK, unless your players get to choose thier team, theres no need to worry about team 5 & 6, just use teams 1, 2, 3 & 4.
Set your Team Index in Island Settings to 4
If you are using the pregame spawnpads as gameplay spawnpads as well, have 2 each of Team 1, 2, 3 & 4.
If your pregame spawns are not your gameplay spawns,
then you need 8 pregame ones set to Island Start on, no Team Index and Priority group 2.
and 8 gameplay spawnpads, 2 pads each of Team 1, 2, 3 & 4. set to Island Start off, Priority Group 1.
I think it’s OK to use Dynamic or Split Evenly in this case
Also I can’t quite remember or maybe it changed, but setting pregame and gameplay spawnpads to Enabled During Phase - Always, works better. It’s been a while my memory is foggy.
