Mod beginner guide

How to install, use and cleanly uninstall Palworld Mods?

1.0 changed the game's core; the biggest traps around modding are corrupted saves and black screens on launch. This guide walks “back up → identify the type → install → use → uninstall cleanly → fix problems,” with real paths at every step.

One iron rule before touching Mods

Back up your save first. Installing, uninstalling and upgrading can all corrupt saves — a backup is your only undo.

Step 1: Back up your save (3 minutes, lifesaving)

Palworld's single-player / invite-code saves live in this folder; copy the whole thing elsewhere and that's your backup:

PlatformSave locationHow to open it fast
Steam / Windows%LOCALAPPDATA%\Pal\Saved\SaveGames\Press Win+R, paste the path, hit Enter; or in Steam right-click Palworld → Manage → Browse local files → Saved\SaveGames.
Xbox / Game Pass%LOCALAPPDATA%\Packages\PocketpairInc.Palworld_*\SystemAppData\Same Win+R paste, then find and copy the matching world folder.
dedicated serverUnder the server directory Pal\Saved\SaveGames\On the machine running the server, copy the entire SaveGames folder.
Backup essentialswhy
Copy the entire SaveGames folder, not just one fileA world is made of several files (world save, player save); miss one and it won't load.
Store backups outside the game directory, named with a dateIn the same directory they can be overwritten by file verification or upgrades; a date tells you which one predates the corruption.
Disable Steam Cloud before restoringSteam → right-click Palworld → Properties → General → uncheck Keep saves in Steam Cloud; otherwise the cloud overwrites your recovered save with the corrupted one.

Know the two Mod types: install methods differ completely

TypeTraitsWhere it goes
Pak type (.pak files)Directly edit game assets, no extra framework; usually building, storage and production mods.Drop into Pal\Content\Paks\~mods(create the folder if it doesn't exist).
UE4SS type (Lua / script / UI)Need the UE4SS loader installed first; usually minimaps, info displays and settings menus.Install UE4SS first, then put the Mod into UE4SS's Mods or LogicMods folder.

If unsure, read the author's install notes — they state whether it's pak or needs UE4SS. Wrong folder = the Mod won't work.

How to install

Casesteps
Installing only pak type1) Back up your save; 2) find Pal\Content\Paks\~mods(create it if missing); 3) drop the .pak in; 4) launch the game to confirm it works.
Installing UE4SS type1) Back up; 2) download UE4SS and copy its dwmapi.dll and Mods and the rest as a whole into Pal\Binaries\Win64; 3) put the Mod into UE4SS's Mods / LogicMods; 4) launch to confirm.
Installing multiple ModsAdd one at a time, confirm it's fine in-game, then add the next; adding all at once makes failures impossible to isolate.

For dedicated servers, confirm the Mod supports the server side and that server and client versions match; many Mods are client-side local effects only.

How to use: a settings menu saves you editing files

Many UE4SS Mods' toggles and parameters can be adjusted by installing a Mod Config Menu in-game via a UI instead of hand-editing JSON config files — hand-editing easily breaks the format and disables the Mod. More and more authors wire their settings into it as the standard config surface.

How to uninstall cleanly: deleting isn't enough, clear the leftovers

1.0 added official Mod management, but itdoes notremove files installed manually the old way. Merely disabling in the manager or deleting the Mod itself can leave the loader and leftovers behind, which still load at startup and cause black screens or corruption.

Uninstall orderaction
1 Back up firstUninstalling can corrupt saves just like installing — copy your save first.
2 Disable rather than delete outrightDisable in the Mod manager first, confirm the game is fine, then deal with files.
3 Clear UE4SS leftoversGo to Pal\Binaries\Win64 and remove the old dwmapi.dll / xinput1_3.dllMods folder,UE4SS-settings.ini
4 Clear pak leftoversGo to Pal\Content\Paks\~mods and LogicMods remove the matching .pak; also clear pre-1.0 PalSchema files while you're at it.
5 Verify filesSteam right-click Palworld → Properties → Installed Files → Verify integrity of game files, to restore modified official files.
6 Test with a copyEnter the game with a copied save first; only after it saves and exits cleanly, apply it back to the real save.

Move files to a “quarantine folder” outside the game directory instead of deleting them outright — if you remove the wrong thing, you can move it back.

Fixing problems: match the symptom

SymptomLikely causeHow to fix
Can't even reach the title screen / black screenOld UE4SS or leftover proxy DLLs incompatible with 1.0.Go to Pal\Binaries\Win64 delete the old dwmapi.dll / xinput1_3.dllModsUE4SS-settings.ini, then verify file integrity.
Title screen works, crashes on entering the worldA Mod the save depends on was removed or is the wrong version.Don't test with the real save — use a copy, reinstall the full previous Mod set, and once it loads, remove them one by one.
Mod installed but nothing happensWrong folder / wrong loader type / missing prerequisite dependency.Check the author page for whether it's pak or UE4SS, if the folder is right, and if a dependency framework is missing.
Save won't loadA Mod that alters save structure leaves corrupted entities and missing references after removal.Don't touch your only save; restore from the earliest clean backup (remember to disable Steam Cloud first).
Quests / events stuck and won't progressAn old Mod altered quest or world data.Go vanilla (disable all Mods) to check if it's still stuck; if Mods cause it, eliminate them one by one.

Troubleshooting principle: protect the save, test only on copies, find the “last known good” state, change one variable at a time — not repeated reinstalling.
