Arnis Tool (1.21.8, 1.20.1) is an open-source map-generation utility built in Rust that lets Minecraft Java Edition players transform real-world cities, towns, or landmarks into detailed Minecraft builds. Using live geographic data from OpenStreetMap, Arnis allows users to generate full-scale replicas of any location from your hometown to world-famous monuments inside a Minecraft world. It’s fast, efficient, and ideal for education, urban modeling, or survival exploration.

Features:
- Real-World to Minecraft Generator
Turn OpenStreetMap (OSM) data into block-based terrain and structures. Select any city, region, or landmark on a map and recreate it directly in Minecraft. - Highly Accurate Proportions
Buildings, streets, and terrain are generated at 1:1 scale by default, ensuring realism and spatial accuracy. - Simple Area Selection
Use a rectangle selection tool to define your area of interest within the Arnis interface. Zoom and pan the map for pixel-precise borders. - Optimized with Rust
Built using the high-performance Rust language, Arnis can handle large-scale generation quickly while minimizing crashes or memory overload. - World Integration
Choose an existing or newly created superflat world in your Minecraft saves directory as the target. Arnis generates everything starting at coordinates (0,0,0). - Command Access
Use/tp 0 0 0
in-game to teleport directly to the generated map area once inside your world. - Use Cases
- Ideal for educational environments, allowing teachers to visually represent real-world geography.
- Great for urban planning, survival adventure maps, or building on real-world layouts.
- Enables creative inspiration by starting with recognizable real-world layouts.

FAQs
Is Arnis Tool safe and open-source?
Yes. Arnis is an open-source tool written in Rust, and its source is available for public use and contribution.
What kind of data does it use?
Arnis pulls data directly from OpenStreetMap, a collaborative and publicly available geodata project.
Can I use it with modded Minecraft?
Yes, but it’s recommended to generate the world in vanilla first and then add mods. Terrain or structure overlap may occur with terrain-altering mods.
Is it performance-friendly?
Yes. Thanks to being built in Rust, Arnis handles large-scale data efficiently and with minimal crashes, even for big cities.
Where is the generated area located in the Minecraft world?
All generated cities or structures are placed at coordinates (0, 0, 0) by default. Use /tp 0 0 0
to teleport there in-game.
