Im using Rorke's weapons and they don't have a pap variant, is it hard to make one?
what programs would I need if any?

Im probably gonna use the standard WAW camo for paped guns and already have ugx weapon editor to change damage and mag size etc.  I DONT have BO1 or 2 if I need them for sounds of paped guns ill just have to use standard WAW pap sounds

You can easily make a pack a punched version of the gun by making a copy and add _upgraded to the copied weapon file (eg. g11_upgraded for the g11). Open it with ugx weapon editor and edit your gun.

For the camo, you need to make a copy of the world model and the viewmodel, with _upgraded or something. The newly copied model file you need to edit and edit the gun materials (not the iron sight materials for example if it has them) to mtl_silver_etching. Make sure you use the new model files as model in ugx weapon editor.

Make sure you add the upgraded gun file to _zombiemode_weapons.gsc, dlc3.gsc and mod.csv.

Edit:

Lol, got 115 posts!

I am now getting an error of unknown item mp5_upgraded (im doing mp5)
I have done all the dlc3_code and zombiemode_weapons stuff, copied the view and worldmodels in root/raw/xmodel
and it says  xmodel_bo1_mp5_upgraded is out of date?

In the files I changed each line after mtl_ to mtl_silver_etching if that's right and its giving me errors...

UPDATE: sorted it! Camo working fine! Now I just need sounds

Here's a tutorial I did a long time ago on it.
