Vault Patcher Mod FAQ
10 questions players actually ask, answered.
What does Vault Patcher actually do in my game?
It replaces hardcoded text inside other mods with localization strings, so text that normally ignores your language setting can be translated. It's a library mod, so it adds no items, blocks, or world content on its own.
How do I get started with Vault Patcher after installing it?
Just install it alongside the mods you want to translate and launch the game. Vault Patcher loads its patches automatically, so there's nothing to configure before your first launch.
Where do I put my own translation patches?
Place your patch files in the Vault Patcher config or resource folder that the mod reads on startup, following the same structure as the existing patches. The mod picks them up on the next game launch.
Why isn't Vault Patcher changing any text in my game?
The most common causes are a patch that doesn't match the target mod's exact string, the target mod not being loaded, or the patch file being in the wrong folder. Check that the mod you want translated is actually installed and that your patch targets its exact hardcoded text.
Does Vault Patcher work with any mod, or only specific ones?
It works with any mod that has hardcoded strings, but only if a patch exists for that mod or you write one yourself. Mods that already use proper localization keys don't need patching.
Can Vault Patcher translate text in mods I don't have a patch for?
No, it only changes text that a patch explicitly targets. If no patch covers a mod's hardcoded strings, that text stays as-is until you or someone else writes a patch for it.
Will Vault Patcher break my other mods or cause crashes?
It's designed as a lightweight library and generally won't conflict with other mods, but a malformed patch can cause errors. If you get crashes after adding a patch, remove that patch file and relaunch to confirm it's the cause.
Does Vault Patcher affect game performance?
Its impact is minimal since it only rewrites strings during loading rather than running continuously. Any noticeable lag is more likely from the mods being patched than from Vault Patcher itself.
Do I need Vault Patcher on both the client and the server?
It's a client-side library, so it belongs on the client where text is displayed. Servers don't need it unless a server-side mod specifically depends on it.
How do I know if a patch is actually working?
Switch your game language to the one your patch provides and look at the targeted mod's text in-game. If the text changes to your language, the patch loaded correctly; if not, the patch string likely doesn't match exactly.
