📋 About This Mod
Summary
I love IMPACT, but it was always a pain to write compatibility patches for, as it required patches for every single weapon in your load order, so a lot of mod added weapons would inevitably get left out, unless you patched them yourself. This mod fixes that.
This mod is a replacement plugin file (this requires assets from the original mod) that adds a scripted patcher that automatically patches all weapons loaded into the game to have the appropriate Shell Casings and IMPACT Data Sets, based on their ammo list or type. This will work with any weapon, in any mod, that is using a Vanilla or DLC ammo list, or any ammo type on a Vanilla list. In addition, version 2. 0 comes with scripted compatibility with Classic Fallout Weapons Remastered.
I have also included scripted checks for weapons using Companion Ammo and non-playable robot ammo, in order to give them the correct Shell Casings and Data Sets. This will work for Vanilla, all DLC, and TTW, without requiring them.
This will relieve the need to patch IMPACT, to make it compatible with any mod that adds weapons or edits weapon data. The mod no longer edits any weapon data at all, which is why an entire replacement plugin is provided. It is identical, save for the added scripts and removed weapon records.
You should no longer need patches for IMPACT, and should no longer need to use your current patches.

IMPACT - Compatibility Edition (JIP LN) is a replacement main plugin for the IMPACT mod that automatically patches all weapons in Fallout: New Vegas, including DLC and modded weapons, to have appropriate shell casings and impact data sets based on their ammo types.

✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust: 5,324 endorsements and 381k downloads — this is a must-have for IMPACT users.
- Automatically patches every weapon from DLC and mods, saving you from manual patching headaches.
- Keeps your game visually consistent by matching casings and impacts to ammo types, even with a massive mod list.
⚠️ Cons
- Requires JIP LN (JIP Line Separators) as a dependency — if you don't have it, you'll need to install it first.
- Only works with the IMPACT mod — if you're not using IMPACT, this plugin is useless.
- Last updated in November 2025, but if you're on an older game version, you might need to check compatibility with your setup.
For Fallout: New Vegas modders who use IMPACT and have a heavily modded game with many weapon mods. If you want your shell casings and impact effects to look right across all weapons without manual patching, this is for you. Skip if you don't use IMPACT or prefer a more lightweight visual overhaul.
💡 Beginner Tips
- Make sure you have JIP LN installed and activated before adding this plugin, or the game may crash on load.
- Load this plugin after IMPACT and any weapon mods in your load order to ensure it patches them correctly.
- If you use a mod manager like Mod Organizer 2, let it handle the file overwrites to avoid conflicts.
