Install PalSchema

PalSchema runs JSON data-table mods on top of UE4SS. Where it installs, what it requires, and how PalSchema mods are laid out in Palworld 1.0.

PalSchema mods are JSON data-table edits: no compiled code, just structured changes to the game's existing tables. That covers things like pal stats, drop tables, recipes, and spawn weights.

PalSchema is the right loader when a mod is changing existing values rather than adding new behavior. If a mod page's loader badge says PalSchema, expect a JSON payload rather than a script.

Before you start

Install UE4SSPalSchema is a UE4SS mod itself, so this comes first.

This is the framework archive itself, not an individual mod. Extract it directly into the path shown for your platform.

Install PalSchema

Install UE4SS first
PalSchema will not load without the framework already in place. See the UE4SS guide if you have not done this yet.
Download the PalSchema framework
Get it from its PalMods entry so it matches the build tested against Palworld 1.0.
Extract PalSchema into UE4SS's Mods folder
Use the framework path shown above for your platform. PalSchema creates its own mods subfolder once installed.
Drop individual PalSchema mods into that folder
Use the per-mod path shown above, one subfolder per mod.
Launch and verify
Start Palworld. PalSchema loads through UE4SS, so a working UE4SS load means PalSchema mods loaded too.

FAQ

Frequently asked questions

Can I install PalSchema without UE4SS?

No. PalSchema is a UE4SS mod, so UE4SS has to already be installed and working before PalSchema mods will load.

Does PalSchema replace pak mods?

No, they solve different problems. Pak mods package new or replaced assets. PalSchema edits values in the game's existing data tables. A modlist can use either, or both.

Why would I use PalSchema instead of a Lua mod?

If a mod is only changing existing values, like a drop rate or a recipe cost, PalSchema's JSON edits are a lighter, more contained way to do it than a full Lua script.
