What does CB: Compressed Blocks add?
Overview
This mod allows players to compress multiple blocks into a single block or multiple items into an item crate, saving
space in the world.
The compressed variants can store up to 9 blocks/items of the same type, and with multiple levels of compression, a
single compressed variant can hold as many as 3,486,784,101 blocks or items.
This allows players to store vast quantities of blocks/items in a single block.
The compressed block can be decompressed to retrieve the original blocks, making it a versatile tool for building and
storage purposes.
Currently, the mod offers 264 different types of compressed blocks and 179 types of crates.
