Missing materials or you used the Weapon Editor and the notetrack to hidetags illness caught up too you.

Check asset viewer, see if the model shows up in there, if so, check the last 2 things I mentioned.
Second ones not likely since it's trying to hide tags that don't exist I'm just covering the 2 main possibilities (Also making sure it's in your _zombiemode_weapons script for precaching)

You have to go to your raw/immages folder and copy every texture needed for the weapon to your modname/immages folder. Then check the immages inside the modbuilder and recompile your mod.

Depends if their streamed or not in the sound alias.
If it's WaW sounds your using then it's just the WeaponFile that needs fixing.
Check first before cluttering IWD with unneeded files, and make sure you have added the soundalias to your mod.csv or mapname.csv under zone_source.
