You Just must delete the models from: Wraith, Poison Zombie, Chem Zombie.
Why? For some reason the game is More Stable when you only use the models of the Fast Zombie, The Zombie and the Sawyer (For Chem).
Now To Remove the Models from the Zombie who cause Crashes
Go to this line inside the file "es_ZS" (addons\eventscripts\ZS):
es playerset model event_var(userid) "models/player\pil\poison\poison.mdl"
And replace it with this one:
es playerset model event_var(userid) "models/player\pil\classic.mdl"
go to this line:
(TAKE NOTE THAT IF YOU WANT TO USE A MODEL THAT DO NOT CAUSE CRASH FOR THE CHEM ZOMBIE IGNORE THIS STEP)
es playerset model event_var(userid) "models/player\pil\stalker2\stalker.mdl"
Replace with:
es playerset model event_var(userid) "models/player\pil\classic.mdl"
Go to this line:
es playerset model event_var(userid) "models/player/pil/crispier/crispy.mdl"
Replace with:
es playerset model event_var(userid) "models/player\pil\classic.mdl"
Now Everyone here dont want to shoot a Chem zombie thinking that he is a normal Zombie (Cause the Model) I use the model of the sawyer, now If YOU want to use it just download it from here:
Mediafire.com
and go to the line (If you didn't replace it)
es playerset model event_var(userid) "models/player\pil\stalker2\stalker.mdl"
and Replace it with
es playerset model event_var(userid) "models/player/zombie/sawyer/sawyer.mdl"
If you replace the Line es playerset model event_var(userid) "models/player\pil\stalker2\stalker.mdl"
Dont worry, Go to this line
[Zombie Survival]#default You are a#lightgreen chem zombie
and down there is the line
es playerset model event_var(userid) "models/player\pil\classic.mdl"
Just replace it with:
es playerset model event_var(userid) "models/player/zombie/sawyer/sawyer.mdl".
And now You're Done.
Save the File, restart your server and Enjoy a server 90% More stable and with Custom Skins for zombies. :D
