    Compatibility

    This replacer is compatible with animation mods that replace vanilla Deliverer animations and use vanilla deliverer keywords

    This includes:

    • []Deliverer Animation Replacer Pack by WarfightersWorkshop - https://www.nexusmods.com/fallout4/mods/46568

      []Pistol Reanimation Pack by The Shiny Haxorus - https://www.nexusmods.com/fallout4/mods/19248

    • Fiddler's Deliverer Animation Replacer by FiddlerGreen - https://www.nexusmods.com/fallout4/mods/27609

      Installation
      1. Download and install: Walther P99 by TrophiHunter - https://www.trophihunter.com/fallout4-mods/walther-p99 (this mod downloadable outside of the Nexus Mods website)

      2. If you want to use a Deliverer animation replacer, such as Deliverer Animation Replacer Pack by WarfightersWorkshop, you can install that now as well

      3. Make sure the esp for that mod is activated and all the assets from it are in your Fallout 4 data folder

      4. Install this mod. Select the replacers you want in the installer and click finish

      Troubleshooting
      1. Place the replacer esp(s) lower or last in your load order. It's possible you have another mod activated that is overwriting the replacer data or your mod manager is auto sorting the esp's in a poor configuration

      2. If an NPC/Companion weapon is broken, you can individually update them by entering the console, selecting the NPC, and entering the "Resurrect" console command. You will have to do this one-by-one for each NPC. If the NPC/Companion isn't equipping their replaced weapon after the resurrect command, open the console, select them, then enter the "openactorcontainer 1" console command. You can use this console command to view their inventory and force them to equip their replaced weapon and ammo or force them to equip another weapon altogether

      3. Take the replaced weapon to a weapon workbench and re-craft the weapon parts. Crafting
