FAQ about SP map making

[Donneck]

Hi

I've just read a map editor hints in novahq.net.
I've got a question making a sp map for DF Blackhawk Down (Team Sabre):

I just can't manage to place fences in the hillside.
changing (lowering) the Z value of the fence, makes sink one end of the fen=
ce in the terrain, and ok at the other end, if I change the Z value the mak=
es floating in the air, while the other side is correctly on the ground. I =
tried change the pitch value but it makes worst.

What should I do. Do I have to place fences in flat terrain ?

Other question:
I made a small VW bus going across the map. At the end the minibus starts g=
oing on his unpredictible way (even with checking Wp Loop or not loop) How =
do I make it STOP when arrives to last waypoint ?

and finally:
How do I make PaveLow to open backdoor ?
and also: helicopter arrives at LZ, then should go forward when insertion i=
s done ?
Should I use the "event" thing ?

thx in advance
