So Im trying to add a cod 5 ready weapon from cfg factory and I can't get it to work, I followed the steps you would normally do, and it didn't show up in game. I tried adding it as a ugx gun and putting it in ugxm_guns.iwd. Again no luck. How do you do this? There's no ingame errors, nothing missing it's just not there in the box, or give all.

id say find a weapon you want to replace and rename the new gun weapon file to that guns and delete the replaced weapons file

Make sure you have the xmodels and xanims included in a non-ugx fastfile and make sure you use an existing weaponfile name so that the scripts don't need to be edited.
