Is there a way to have for instance four people on a team each spawn at four different spawn nodes, but the same nodes every single time. Thanks in advance.

You would have to manually force spawn each unit at the node you want it to spawn at. You can do forced spawning as soon as someone dies or when they select a unit class.

So when I select my unit class. It will spawn, somewhere then everyone else spawns where I want them to?

How do you do this?
