Java structure NBT guide
A .nbt export saves your build as a normal Minecraft structure that you load with a structure block.
New to .nbt?
Minecraft saves its own villages and igloos this way. Put the file in your world folder, place a structure block, type the name, and the build appears. No mods needed.

What is .nbt?
Minecraft Java uses .nbt files for its own structures, like villages and temples. The file lists every block in the build and where it goes. Your world reads it from its structures folder, so you do not need any mods.
How to use a .nbt export
01
Export the structure
Pick “nbt single” for one file, or the chunked option to get 48 x 48 x 48 pieces of a big build.
02
Add it to your world
Put the file in your world's structures folder. If the world was open, close it and open it again.
03
Load it with a structure block
Get a structure block with /give @s structure_block, set it to Load, type the structure name, then load the build.
When to use it
Pick .nbt when you want to add the build to a world you already play, you are making a data pack, or you would rather not install a mod.
Things to watch out for
A structure block only places 48 x 48 x 48 blocks at a time, so Bloxelizer can also export a big build as several 48 x 48 x 48 pieces that you load one after another. Your Minecraft version also has to know every block in the build.
Useful tips
Keep the file name simple
Use lowercase letters and no spaces, or the game may not find your structure.
Look before you load
The structure block shows an outline first. Check it so you do not build on top of something you want to keep.
