Installation

1. Config Entries

Open your config/compressiumblocks.json file and add the following to the existing array:

[
...
  {
    "name": "vault_cobblestone",
    "nestedDepth": 9,
    "isBlockOf": false,
    "baseResourceLocation": "the_vault:vault_cobblestone",
    "particlePath": "the_vault:block/vault_cobblestone",
    "baseBlockModel": "the_vault:block/vault_cobblestone",
    "type": "block"
  },
  {
    "name": "vault_stone",
    "nestedDepth": 9,
    "isBlockOf": false,
    "baseResourceLocation": "the_vault:vault_stone",
    "particlePath": "the_vault:block/vault_stone",
    "baseBlockModel": "the_vault:block/vault_stone",
    "type": "block"
  }
]

Important: Merge the entries, don’t replace the entire file!

2. CraftTweaker Scripts

Extract the crafttweaker_compressium_scripts.zip to the scripts/ folder so that the following files are available with the other crafttweaker scripts:

• compressium_vault_cobblestone.zs
• compressium_vault_stone.zs

5. Datapack

Copy the vault-compression-datapack.zip folder to your world’s datapacks/ folder:

• Location: saves/[YourWorldName]/datapacks/
• For servers: [ServerFolder]/[WorldName]/datapacks/

4. Resourcepack

Copy the Vault-Compression.zip resourcepack to your instances’ resourcepack/ folder and enable it in-game (Options > Video Options > Resource Packs).

Usage

Compress: Place 9 blocks in a 3×3 crafting grid to compress one level
Decompress: Place 1 compressed block in crafting grid to get 9 of the previous level

Compression Levels:

• 1x: 9 blocks
• 2x: 81 blocks
• 3x: 729 blocks
• 4x: 6,561 blocks
• 5x: 59,049 blocks
• 6x: 531,441 blocks
• 7x: 4,782,969 blocks
• 8x: 43,046,721 blocks
• 9x: 387,420,489 blocks

Troubleshooting

Blocks don’t appear in JEI/Creative:

• Make sure you added the config entries to compressiumblocks.json
• Restart the game after adding config entries

Can’t craft compressed blocks:

• Ensure CraftTweaker scripts are in the scripts folder
• Check CraftTweaker logs for errors

Blocks have missing textures:

• Make sure the resourcepack is enabled
• Check that resourcepack files are in the correct location

Blocks don’t drop when mined:

• Ensure the datapack is installed in your world’s datapacks folder
• Use /datapack list to verify it’s loaded
