Okay… I am trying to design a custom pistol that uses custom ammo. Nothing terribly fancy. I dont need to re-colorize them like the rainbow, stock icons are fine. In this case I was trying to use the machinedpistol and advanvedbullet for the weapon and ammo base files. I started with making a folder in the “Mods” directory called “TheSilencer” and as far as I know, I only need the 3 core files, Genericmod (Level), primalgamedata_BP, and test game mode. all renamed “GenericMod_TheSilencer”, “PrimalGameData_BP_TheSilencer”, and"TestGameMode_TheSilencer" in that first main folder. From there I have two subfolders. TheSilencerGun and TheSilencerBullet. The gun/weapon directory has only two files. EngramEntry_TheSilencerPistol and PrimalItem_WeaponTheSilencerPistol. For the ammo folder, the same, only two files. EngramEntry_TheSilencerBullet and PrimalItemAmmo_TheSilencerBullet.
primalgamedata_BP has the engrams for the gun and ammo listed as additional engrams.
