hi murphy
i played ur map in a network and ran in a problem.
this is it what it looks like when i play the map as a client on a server:
i see no helis, or droppods.
the zeds appear like this
i hear the sound of the helis but they are not visible.
another example of the same problem.
noone else in this thread mentioned this so it is possible its only me:
i read ur post about how frustrating it gets by now for u doing this map.
here comes my suggestion:
forget the helis. skip the droppods. spawn the zeds conventional.
the idea to fly and drop them in is ubergreat but when it starts draining u like this its time to stop at some point.
some possibilitys would be: some spawns in the water behind the upper damwall and let them climb out of the water. let them jump over the fences. if jumping looks absurd (and it does if they jump to far and to high) let them walk down the hills and give them some obstacles to climb the fence from their side. let them jump out of the water on the lower dam side on the brigde. use the effekt robot uses in survival and it will look impressive. let the zeds march out of the tunnel. let them walk down the hills near the tunnel. spawn them between the damwall and the bridge in the white water. with ur actual pathnodes they walk out realy nice.
do this and then u have it all: nowhere to run for the players, zeds from all sides, great optics and stable gameplay. no more problems
as u pointed out by urself: the players does care little where the zeds come from. they are not intrested in how u spawn zeds in their faces as long they can believe it.
maybe u do a version of ur map with conventional spawning and release it. just to get a little solace for u and a awesome map for us
