📋 About This Mod
An all-in-one modding utility for editing, translating, comparing, and compiling localization files, with a visual in-game menu designer and installation-ready project outputs
All-in-one utility for Witcher 3 mod authors to build localized in-game menus and manage localization files. It visually creates nested menus, auto-generates XML, WitcherScript, CSV, and .w3strings outputs, and supports translation into every game language. It stands out with drag-and-drop project organization and compare/merge tools for localization files.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Turns a tedious job (hand-editing XML and WitcherScript for menus) into a visual drag-and-drop builder.
- Outputs installation-ready XML, WitcherScript, CSV, and .w3strings files without extra conversion steps.
- Includes translation and merge tools, so you can handle multiple languages and mod conflicts in one place.
⚠️ Cons
- Fresh tool with 0 endorsements and only 4 downloads, so it hasn't been battle-tested by the community.
- Smaller edition requires a separate .NET 10 Desktop Runtime install unless you grab the Runtime Included version.
- Windows-only .exe leaves Mac and Linux mod authors out.
For Witcher 3 mod authors who need to create in-game configuration menus and localize their mods across multiple languages. Perfect for those tired of writing XML and WitcherScript by hand—the visual builder does the heavy lifting. Skip if you're a player looking for gameplay mods; this is a development tool for mod creators, not something you install into your game.
💡 Beginner Tips
- Grab the Runtime Included edition to skip the .NET 10 Desktop Runtime setup entirely.
- Use the visual menu builder to layout your mod's options first, then export the XML and WitcherScript.
- When merging localization files, keep a backup of your original .w3strings and CSV exports to compare against.
