Compatibility & Updates

A Palworld patch can quietly break your tools and mods. The root cause is almost always the same: your build-specific pieces no longer match the new game build.

What a game update can break

Section titled “What a game update can break”
  • Mappings (.usmap). The most common casualty - your tools misread assets until you get a mappings file for the new build.
  • UE4SS. UE4SS is rebuilt per game version; an old build can fail to load or crash. Wait for a build made for the new version.
  • Frameworks that load into the game (anything depending on UE4SS) - re-check they’re updated for the new build before relying on them.
  • Asset and DataTable paths / names. These can be renamed or restructured; a path from an old guide may no longer exist.

The post-update checklist

Section titled “The post-update checklist”
  1. Don’t assume your old files still work. Treat the setup as suspect until verified.
  2. Update mappings to one generated for the new build (or generate your own).
  3. Update UE4SS and any loaded frameworks to their new-build versions.
  4. Re-extract from your own install rather than reusing old exports - names and paths may have moved.
  5. Re-test each mod and fix what broke.

Palworld 1.0: use the right UE4SS build

Section titled “Palworld 1.0: use the right UE4SS build”

A very common 1.0 problem: installing UE4SS/PalSchema causes a Steam-ID mismatch bug - you’re forced into the character-creation screen, the game acts bricked, or mods simply never load. The cause is grabbing the upstream or “dev” UE4SS build instead of the Palworld-specific one.

  • Fix: use Okaetsu’s Palworld-specific UE4SS (the experimental-palworld RE-UE4SS release), not the dev/upstream version, and follow the PalSchema installation docs (okaetsu.github.io/PalSchema/docs/installation) which pair the correct UE4SS + PalSchema. UE4SS goes in Pal/Binaries/Win64, PalSchema in the ue4ss Mods folder.

Updating the Palworld Modding Kit for 1.0

Section titled “Updating the Palworld Modding Kit for 1.0”

After the 1.0 update you do not have to rebuild your PMK project from scratch. The modding kit was updated for 1.0; you can drag-and-drop the updated kit files into your existing project rather than redoing setup. Follow the “Updating the Palworld Modding Kit” guide on the official wiki.

Why PalCodex marks page versions

Section titled “Why PalCodex marks page versions”

Because this drift is constant, every page here carries a version badge (verified-1.0, needs-review, or legacy early-access). When you read a dated guide, keep the approach but re-verify the specifics against your current build. See Palworld 1.0 vs early access.
