Thanks a tonne Banks, or should I say Danke Sehr?
Still a NoGo as host, guess it works for SP and from a ded.server as described (but we don't have a ded.server exe yet do we? just a second license install where the player runs to another computer flying?)
Tried with "null" as player but still no marker.
In Arma, where I come from, we have "IsMultiplayer" and "IsDedicated" along with a lot of player/server procedures to cope with remote players, hosted server player and dedicated server with no player at all - sure miss them here.
(I prefer flying singleplayer as multiplayer-host on locked server due to MP features - same as in ArmA)
Guess this will work in the "sequel" one day..
