One library everywhere
Your schematics live in Heavymatica Cloud. The library you open on one server is the same one you find in single player, on another server or on another computer.
Heavymatica
Schematics for Minecraft with a simple placement UI and a cloud library that follows you to every world and server.
Heavymatica shows a building plan as a ghost in your world and helps you build it, block by block. It does what Litematica does for most players, with far fewer menus: pick a schematic, put it where you want it, lock it, and build. It runs on Fabric and on NeoForge for Minecraft 26.1.2, on the client alone, so it works on any server.
Simple placement
Hold the remote, move, rotate and mirror the ghost, then lock it in place. Everything else is on one wheel.
See what is wrong
A locked placement compares itself with the world and marks wrong and missing blocks. A pointer leads you to the nearest mistake.
Build in layers
Show one layer, a range of layers or the layer at your feet, and only the blocks you hold if you like.
Materials
See what the build still needs, what you carry and what you are short of. Swap block types per placement.
Easy Place
Right-click a ghost to place exactly the planned block, or let the mod stop you from placing a wrong one.
