Example Mods made with RobCo Patcher

Natural resistances

Overhauls the races of Fallout 4 and adds Fire, Cryo and Electrical resistances.

This is a template for adding weapons to the game.

This template is pre-configured and has several options for you.

Container, NPCs, Quest Rewards and Vendor.

Just enter your plugin name and the form ID of the weapon and delete all other entries you don't need.

Simple, easy, RobCo!

Why use RobCo Patcher?

The patcher is capable of patching your load order and fixing incompatibilities on runtime!

This mod was created for Better Locational Damage, but can also be applied for other mods.

Many people have issues with Better Locational Damage, because they use many mods that add new NPCs or change existing NPCs. This leads to a bad user experience. RobCo Patcher fixes that!

For example, you are a mod author and create new ammo types for weapons. With RobCo Patcher, you can easily create one config file to patch them all! No ESP or ESL files. One config with all weapon mods you want to change and done! No incompatibilities no patches! Easy and simple!

Configuration

RobCo Patcher comes with an ini while located next to the .dll file, where you can enable and disable patcher options.

How does it look like?

Example, patching races

filterByRaces=Fallout4.esm|00013746:filterByKeywords=Fallout4.esm|0002CB72:changeAVIFS=Fallout4.esm|000002D4=100,Fallout4.esm|000002E3=100:spellsToAdd=Better Locational Damage.esp|0101750F , Better Locational Damage.esp|0101B207

This modifies the HumanRace from Vanilla. It looks up the race with filterByRaces and also looks for similar races, which have the keyword ActorTypeHuman with filterByKeywords. Once it found the records, it sets the AV 2D4(Health) to 100 and 2E3(Damage Resist) to 100.

With spellsToAdd we add two spells from Better Locational Damage, which add perks to a race.

Weapon (Ammo Change 10mm Pistol to . 308)
