This mod allows you to polish up your creativity and optimize your redstone systems. Indeed, the size of blocks placed in a little blocks is divided by eight compared to its original size, so you can place 512 blocks instead of one. Be careful though with the size of your creations because the resources (memory, gpu / cpu …) increases proportionally with it.
All this mod requires is for you to place a dirt block into a crafting table and you’ll get the Little Blocks Wand. A simple left click on an empty cube turns that into the Little Blocks cube and you’ll now see that you have many smaller cube spaces within that one cube to place your blocks.
