PalSchematics

Add Palworld schematics to a save file — single player or dedicated server. All 600-odd schematics, grouped by category, tier, rarity and workbench, with the game's own icons so you can find what you want at a glance.

PalSchematics is original software. Save parsing uses the community palworld-save-tools library (MIT); schematic data comes from paldb.cc.

What it does

Schematics in Palworld are ordinary inventory items. While one sits in your backpack it unlocks the matching recipe at the workbench — it is not consumed, and it can be dropped or handed to another player. PalSchematics simply puts the item into a player's backpack in the save file.

• Every schematic paldb lists — weapons, armor, accessories, structures, pal gear, raid slabs.
• Grouped how you think about them — by category, by category and type, by tier (Schematic 1–4), by rarity, by workbench, or by item so all four tiers of one weapon sit together.
• Search across schematic names, the item they unlock, and internal codes.
• Icons for every entry.
• Dedicated servers supported — the app reads every player in the world and lets you pick one by name.
• Double-click any entry to open its paldb page.

How to run

1. Close Palworld, or stop your dedicated server. A running server holds the world in memory and overwrites the file on its next autosave — your edit would vanish. PalSchematics refuses to write if it sees the file change underneath it, but it cannot stop a server that starts saving afterwards.

2. Double-click Run PalSchematics.bat (needs Python 3.10+; it sets up its own environment on first run).

3. File ▸ Open Level.sav

   • Single player: %LOCALAPPDATA%\Pal\Saved\SaveGames\<id>\<world>\Level.sav
   • Dedicated server: Pal\Saved\SaveGames\0\<world>\Level.sav

   The Players folder must sit next to Level.sav — that is where each player's inventory is located.

4. Pick the player, tick what you want, press Apply to save.

oo2core_9_win64.dll

Palworld 1.0 saves are Oodle-compressed, so unpacking one needs the game's own runtime. Copy oo2core_9_win64.dll from your Palworld install (Steam\steamapps\common\Palworld\Pal\Binaries\Win64\) into this folder. It is not distributed here.

Safety

Editing a save is editing a save, but this tool is built to fail safely rather than quietly.

• Round-trip check. Before anything is modified, the save is decoded and re-encoded and the result must match the original byte for byte. If this build cannot represent your save losslessly, it refuses to write at all.
• Written in the same format it arrived in. A 1.0 server save goes back as Oodle/PlM, not re-packed as zlib.
• Verify before swap. The new save is written to a temporary file, re-opened from disk, and checked for the items you asked for. Only then is it swapped in, with an atomic replace. A failure at any stage leaves the original untouched.
• File-changed detection. If Level.sav changes on disk between opening and applying — the signature of a server still running — the write is refused.
• Backups, on by default. A timestamped .bak is written next to the save. To roll back: stop the server, copy the .bak over Level.sav.

Inventory limits

The app reads how many slots the selected player actually has free and shows it under the save path:

Psyonicar's backpack: 35 of 51 slots used - 16 free - room for 11 schematic(s) this apply

By default it will fill those free slots but always leave 5 empty. A completely full Palworld inventory is where odd things happen — pickups landing on the ground, items seeming to vanish — so the bag is never filled to the brim. Anything that does not fit is reported, not silently dropped; make room in-game and apply again.

Switch the limits off in the Safety box and every free slot is fair game. Even then the container's real capacity is a hard bound: the app will never write a slot index the container does not have.

Building from source

See BUILDING.md for the full instructions, including a one-directory build if a scanner objects to the single-file one.

Building the .exe

.venv\Scripts\pip install pyinstaller
.venv\Scripts\pyinstaller PalSchematics.spec

dist\PalSchematics.exe is a single ~12 MB file that needs no Python. Ship it with a note telling people to drop oo2core_9_win64.dll next to it — that file is Palworld's, so it is deliberately not bundled.

Some antivirus tools flag any PyInstaller executable purely because of how it is packed. If that happens, the source version runs the same program.

Updating the catalog

When Palworld adds schematics:

pip install pillow
python tools/build_data.py

This rescrapes paldb, refreshes palschematics/data/schematics.json and pulls any missing icons. paldb's CDN rate-limits bulk downloads, so the icon step is deliberately slow and can be re-run — it keeps what it already has.

Checking it against your own save

python tools/selftest.py "C:\path\to\a COPY of Level.sav"

It exercises the catalog, the round-trip guarantee, the safety policy and the write path, then proves that removing the added items reproduces the original file byte for byte. It writes to the file you give it — use a copy.
