Pak Mods, LogicMods & Load Order

Updated

Tell resource paks from UE4SS LogicMods, install Workshop or manual packages correctly, and diagnose file conflicts without guessing at folder names.

16 min read Researched for 1.0 Sources included

A .pak extension tells you that Unreal packaged the files; it does not tell you how Palworld should load them. A resource pak can replace or add cooked content through the official Paks rule. A LogicMod is also cooked into a pak, but contains Blueprint behavior that UE4SS discovers through the LogicMods path. Put the right archive in the wrong family and it can be present on disk without ever executing.

Palworld’s official package format removes that guesswork: Info.json declares the InstallRule, and the loader deploys the package to the corresponding runtime location. For a manual release, the author must state whether it is a resource pak or LogicMod and preserve any companion .ucas and .utoc files.

Install an official package

  1. 01

    Check the declared rule

    On Workshop, confirm whether the item is Paks or LogicMods and install any required UE4SS item. A LogicMod without its runtime is not a plain pak fallback.

  2. 02

    Subscribe with dependencies

    Use Required Items or Subscribe to all. Let Steam finish every Palworld Workshop download.

  3. 03

    Enable it in Mod Management

    Turn on the mod and its dependencies under Options → Mod Management, then save and allow the game to restart.

  4. 04

    Test an observable result

    Use a disposable world or backup and verify the item, asset, UI, or Blueprint behavior the author documents.

  5. 05

    Add possible conflicts last

    When two packages modify the same cooked asset or system, test each alone before evaluating their combined behavior.

03Manual path

Manual resource pak location

<Palworld folder>/Pal/Content/Paks/~mods/ExampleMod

Legacy/manual distribution only. Keep `.pak`, `.ucas`, and `.utoc` companions together exactly as the author packages them.

04Manual path

Manual LogicMod location

RequiresUE4SS (Palworld fork: Okaetsu experimental-palworld)BPModLoaderMod for Palworld
<Palworld folder>/Pal/Content/Paks/LogicMods/ExampleMod

LogicMods require a compatible UE4SS runtime. The cooked pak filename and internal mod folder identity must agree with the author’s project.

05Load order

How conflicts actually present

Two resource paks can replace the same virtual asset. One result wins or the combination fails, but a successful boot does not prove that both changes survived. LogicMods can conflict at a higher level by registering overlapping hooks, replacing the same Blueprint behavior, or assuming another object is unmodified.

Build a conflict test from an unmodded baseline: package A alone, package B alone, then A plus B. Record the exact observed effect and fresh logs. If the combined result differs, use an author-provided patch; moving files among ~mods, LogicMods, and Workshop directories only changes the loading mechanism and can create a second problem.

06Diagnosis

A pak is present but the change is missing

  • Correct family

    The author identifies the release as Paks or LogicMods, and you used that loader rather than guessing from .pak.

  • Complete file set

    All .pak, .ucas, and .utoc companions from an IoStore package remained together.

  • Compatible runtime

    A LogicMod has the required UE4SS build; a resource pak is not being forced through LogicMods.

  • Unaltered package identity

    You did not rename a LogicMod pak away from the identity used by its cooked ModActor folder.

  • No overlapping replacement

    Test the package alone against a clean baseline before assigning blame to load order.

FAQ

Frequently asked questions

Does every .pak go in the same folder?

No. Resource paks and LogicMods are both packaged files but have different purposes and loader paths. Use the author’s declared type or the package Info.json InstallRule.

Do LogicMods require UE4SS?

Yes. LogicMods are Blueprint logic discovered through the UE4SS Palworld runtime. A plain Paks package does not inherently require UE4SS.

Can I fix a conflict by adding z_ to a filename?

Do not treat that as a universal solution. Conflicts can involve virtual asset paths, package mounting, Blueprint logic, or hooks. Use an author-provided compatibility patch or choose one package after a controlled test.

Should I copy only the .pak from an archive?

No. If the release contains `.ucas` and `.utoc` companions, keep the complete set together. Splitting an IoStore package leaves it incomplete.
