I know you can pass -Port to set the port, but -QueryPort doesn’t seem to work.
I notice that Chivalry does support this as a command line param, and they use UDK. Maybe they have engine source access and have implemented it themselves.
This is kind of a pain when setting up dedicated servers…
Update: It seems UT3 also allows -QueryPort command line param. So it really does seem like UDK should support this, and I’m wondering if i’m doing something wrong…
