Palworld Modding Guide

An extensive guide on how to mod Palworld. I will be honest I am mainly putting this here so I can keep reminding myself.

HUGE NOTE: Nearly everything here has been parroted by me since I am using this as my own personal notes. So go thank NorskPL and the Palworld Modding Community Discord Server for being the ones to make this all possible.

ANOTHER HUGE NOTE: If you have any issues I have a small section at the bottom dedicated to the ones I found. If your issue isn't there then check the Discord, also linked below!

Note

This mainly handles asset swapping. If you want to do some blueprinting and modifying of the game code use This instead.

Requisites

FModel

UnrealPak

Unreal Engine

Extracting Files

Use FModel

FModel Tutorial

Run Fmodel, click on "Add Undetected game", type any name and enter the directory path to Palworld game. Click on the blue plus button. Unreal Engine version of the Palworld game is 5.1.1, so use GAME_UE5_1 setting. Go to settings and enable Local Mapping File Select Mappings.usmap file under Mapping file path Now you're able to explore game files and export textures/models and stuff!

Note: Fmodel requires .NET 8.0 Desktop Runtime installed on your computer!

Get the right version of Unreal Engine

Current version -> Unreal Engine 5.1.1

Creating the Unreal Engine Project

Creating Unreal Engine 5.1.1 mod project and preparing it

Select these settings and click create:

After loading process something like this will show up:

Click on platforms and select this setting:

Now go to packaging settings:

Advanced:

Now you can start recreating folder structure in your project and import your assets like png textures and stuff

Folder Structure

Proper folder structure example:

If you've added all the resources you wanted, you can now cook content.

When cooking process is done, go to your project folder, open Saved folder, then open Cooked folder.

Your uasset and uexp files gonna be here.

Creating a PAK file

Mod .pak file creation

You gonna need UnrealPak for this.

Unpack UnrealPak zip and create new folder with projectnamehere_P name

Recreate folder structure to look the same way you see it in fmodel.

Drop uasset and uexp files from your cooked folder to the appropriate folders.

Now drop folder with projectnamehere_P name into UnrealPak-With-Compression.bat

It will generate your mod pak file with name projectnamehere_P

Move that mod pak file into Palworld\Pal\Content\Paks and run the game.

Mod Example

Mod Example (folder structure and unrealpak included) These can be found in the repo, they are named UnrealPak.zip and PalworldModExample.zip

Packaging Notes

Packaging settings for your mod Unreal Engine 5.1.1 project

Use Pak file only Packaging --> Advanced ---> Cook everything in the project content directory

Notes on Texture Names

Texture names:

_B = Base texture

_M = MRAO (MetallicRoughnessOcclusionSpecular)

_N = Normal Map

Normal map can be created with online software or Crazybump MRAO creation tutorial: https://dev.epicgames.com/community/learning/tutorials/6Gn5/creating-mrao-textures-using-free-software

(I will continue to add to this as I learn and understand more about what I am doing)

Issues and Fixes

ISSUE 1 - STICKMAN MODE

If this is you, I have a solution!

I had an issue with scaling, I changed the .psk importer settings in Blender so it did not Scale Down

Then when exporting I scaled the entire FBX down to 0.01

After doing this my mesh in-game did not look like a stickman anymore.

Final Notes

Using all of the steps above I was able to make a Pippa mod, while it may not be 100% perfect that's mainly on my poor rigging :) At least we know that these steps work and that they produce a good result. Any issues lemme know and I will be sure to update this page with more info. If you have any suggestions let me know, I know I need to format the page a bit better for example.
