The lights have come a long way since that code, though I have been designing them for Epoch which has street lights on as standard. The house lights on my github (andgregor) are more efficient and should reduce network lag.
That street light code is still relevant, probably, I would be more...
You need to add an entry to the end of the first line in remoteexec.txt. I would guess that you are using setWaypointStatements on at least one of your waypoints.
I would advise using a unique name during your waypoint creation e.g._axeMsgWP = _axeBusGroup addWaypoint [[6586.8374...
Assuming you are using this script: http://opendayz.net/threads/choochoo-trains-script.12066/#post-35675
As far as I can see there shouldn't be any issues running it on 188.8.131.52. Do you see anything in your .rpt file. Also might be worth adding some debug code in to see what is happening..
Helis will only land at a nearby (within 500m) helipad when the waypoint is set to disembark. Should be possible to force the vehicle to land or at least hover near the ground. Would need sscripting
Am experimenting with markers instead of waypoints.
The snow is a particle effect, which shows as it is still visible when inside a house.
Switching it off, in code, when you are within so many metres of a house or at certain times is certainly doable..
