About this project
What does Compression add?
❗ ATTENTION ❗
If you are updating the mod from version 1.2 to 1.3+, be sure to replace all compressed blocks with regular ones. The mod has been completely rebuilt from scratch, and compressed blocks from the older version will not work (they will disappear).
📦Compression: Compress Blocks to Save Space!📦
How Does It Work?
Simply combine 9 of the same blocks on a crafting table to get one compressed block. Instead of 9 slots, it only takes up one! And the best part is, you can compress it even further! Of course, you can reverse this process.Features:
Multiple Compression Levels: x9, x81, x729, x6561 and x59049 compression levels are available.
Additions: Each block is more resistant to explosions depending on its original hardness, some blocks, such as sand or gravel, have gravity, coal has a specific fuel value in a furnace, etc.
Available Blocks for Compression (71):
- Stones
- Minerals
- Sands
- Planks
- Logs
- Other like Glass
- Items
