📦 Compressy
Squish ANY block into tiny packages of pure storage madness!
✨ What Is This?
Compress 9 blocks into 1. Then 9 of those into 1. Repeat up to 32 times!
| Level | Total Blocks Stored |
|---|---|
| 1 | 9 |
| 2 | 81 |
| 3 | 729 |
| 5 | 59,049 |
| 10 | 3.4 Billion |
| 32 | More than atoms in the universe! 🤯 |
Works with ALL blocks — vanilla and modded — automatically. No config required (but supported)!
🎮 How To Use
Compress
Fill a 3×3 crafting grid with the same block → Get 1 compressed block!
Decompress
Put 1 compressed block in crafting grid → Get 9 back!
That's it. Standard crafting recipes mean full compatibility with automation mods like Create, Applied Energistics, and more!
