Ingot

Ingot is an experimental world storage mod for Minecraft. It replaces Anvil region storage with Ingot Region files for new worlds.

⚛️ Features

• Stores terrain, block entities, entities, and POIs in .ir region files.
• Compresses chunk data with Zstandard.
• Preserves serialized Minecraft NBT, including data added by other mods.
• Detects damaged records and fails explicitly instead of treating them as empty chunks.

New worlds use Ingot storage system. Worlds that already contain Anvil .mca or .mcc region data continue to use Anvil. Ingot refuses to mix the two formats and does not currently convert existing worlds.

💾 Storage

Ingot keeps the usual Minecraft world layout and stores each region type in an ingot subdirectory. Other world files, including level.dat and player data, remain in their usual locations. Dimensions added by other mods will stay in their normal directory paths. Worlds containing .ir files require Ingot to load those chunks. Minecraft and external tools that expect .mca files cannot read Ingot regions.

🐞 Known issues

• Region files are append-only. Replaced chunk records remain in the file, so repeated saves can increase its size.
• There is no conversion between Anvil and Ingot.
• Normal launcher works, production dedicated servers, large modpacks, and long-running performance benchmarks needs verification.
