Arnis generates detailed Minecraft worlds (Java Edition 1.17+, Bedrock Edition, and Luanti/Minetest) that mirror real-world geography by pulling data from OpenStreetMap and elevation sources.

Yes, you can adjust settings like world scale, the spawn point, and whether building interiors are generated.Has Arnis gotten any outside recognition?Yes — it's been covered by Hackaday, Tom's Hardware, XDA Developers, and used in academic work including an AWS case study on elevation datasets and a K-12 flood-education game called Floodcraft.
