libIPN Mod FAQ

libIPN is a library mod that provides the GUI and config-handling code used by Inventory Profiles Next and mirinimi's other mods. It adds no items, blocks, or gameplay on its own, so you only need it because another mod requires it.

Yes, if a mod you use lists it as a dependency. Install it alongside the mod that needs it, matching the same mod loader and game version, or that mod will fail to load.

That's expected. libIPN is a background library, so it has no items, blocks, or creative tab entries and may appear only as a small entry in your mod list.

Open it through the config button on the mod list entry for libIPN, or via the config screen of the dependent mod that uses it. The screen is shared with Inventory Profiles Next, so settings there affect that mod's behavior.

This usually means a version mismatch between libIPN and the mod depending on it, or a missing/conflicting dependency. Make sure libIPN matches the game version and loader of the dependent mod, then restart.

Yes, but it does nothing useful on its own. It only matters when another mod such as Inventory Profiles Next or another mirinimi mod is installed and calls into it.

No. It only handles GUI and config code, so it has negligible performance impact. Any lag you see is almost always from the dependent mod or other mods, not libIPN itself.

Install the libIPN build that matches your game version and mod loader, and make sure it's the same version the dependent mod expects. Remove any duplicate or outdated libIPN jars from your mods folder.

libIPN is published for the loaders its dependent mods support, so pick the build matching your loader. A Fabric build won't work on Forge or NeoForge, and vice versa.

Yes, if no installed mod depends on it. If any mod lists libIPN as a dependency, removing it will stop that mod from loading, so check your mod list first.
