Object problems ingame

[Talibanman]

in zeroedit everything seems allright but when i start the game, in the map there are no other odf:s than those already in its COMMON (cp:s, ammo and health droids etc.), so no odf:s from shipped worlds theres like a big invisible hole in the ground where all of them should be. what am i doing wrong? i've put all of the msh:s needed into my first maps mshs directory as well as tga:s.
help would be appreciated...

First off, what size is your terrain? That often causes problems.

the regular one, though its not entirely used

I have also had this problem. Everything looks fine in Zero editor, and I have followed the documentation exactly, but none of the buildings or vehicles show up. Is there a .lua file or something that I need to change?
EDIT- I figured out the vehicles, but what about the buildings?
