Star settings are default, but there may seem to be different sized stars because I also use Pluto's domesky, which also has stars. I do this for all black sky but different color fog.
It's been so long since I've created an Instant Action map that I don't even know how to do it now. Ahhh!
The way I remember was placing a spawn point of team 1 at one part and a spawn point of team 2 at another, then go into Path and set the DLL to be instant, and save. Any steps I'm forgetting, or am I doing it wrong?
