my dawnville chuch was having that same thing where the would shake there heads and wont climb in the windows
first must have nodes closer for the zombie paths that you start then space them in the houses and around the outside
and they would not go throught the window till i thined the wall down ,after that they worked fine ,maybe you have stacked the sandbag walls a little thick at your base "bottom, or floor" and node overlaping can cause pause and head shaking ,like nodes to far apart

Hey guys...
I've just started getting into this zombie map making, i've made plenty of MP maps, but these zombie maps are sure tough to figure out..

I followed the video tutorials, twice even, each time I get the same error (see screenshot), I've even created my own map with the zombie spawns, player start and script_structs and path nodes and I STILL get the same error...

I'm beginning to think that the error I have is in the _zombiemode.gsc file in raw/maps. The thing is..i've never touched that file..

any help? I've now spent about 20 hours and have nothing to show for it :(

It said "Map must have at least one visible non-sky surface" in CodWaWRadiant

Like WTF!

You should start a new thread, this is over a year old.

But too answer your problem. Do you have a skybox made corrrectly, it sounds like you didnt make it hollow or texture it a sky texture.
