How do I load the world?

Unzip the download and place the world folder in .minecraft/saves, then pick it from your singleplayer world list.

Does this convert a full existing world?

No. It builds a new Java world around a single .schem; it does not migrate an existing world or its terrain.

Does the .schem need to be Sponge format?

Yes. This route reads modern Sponge .schem files. Legacy .schematic files should be upgraded with the schematic-to-schem route first.

Do I need WorldEdit installed?

No. The output is a vanilla Java world folder, so you can load it without WorldEdit or any mods.

Convert .schem to Java world

Turn a WorldEdit or Sponge schematic into a standalone Java world. Bloxelizer reads the .schem palette and packages the build as a Java world folder you can load in singleplayer.

The .schem and Java world formats

A Sponge .schem stores one region of Java block states for WorldEdit and FAWE — data to paste, not a playable save. A Minecraft Java world is a folder of region (.mca) files and a level.dat. The conversion writes the schematic into a fresh Java world folder, delivered as a .zip, so it loads as its own singleplayer save.

How to convert .schem to Java world

Upload your .schem file in the converter below.

Review the build in the 3D or layer preview.

Keep the Java world format selected and download the .zip, then unzip it into your saves folder.

When to use this conversion

Use this route to open a schematic as its own Java world without WorldEdit or pasting it into an existing save.

Compatibility notes

Load the world in a Minecraft version that supports the schematic's blocks. The build is placed in a generated world; newer blocks need a matching client.
