What is a .prefab.json file?

It is Hytale's prefab format — a JSON description of positioned blocks using Hytale's block names — that you can import into a Hytale project.

Are Litematica regions preserved?

All regions are merged into a single prefab. The prefab format does not represent Litematica's named region layout.

Will every block map to Hytale?

Common blocks map to a close Hytale equivalent. Blocks without a match are reported so you can review or replace them.

Do I need the Litematica mod?

No. The conversion runs in your browser and outputs a Hytale prefab; the Litematica mod is not required.

Convert .litematic to .prefab.json

Bring a Litematica build into Hytale. Bloxelizer reads the .litematic regions, maps the blocks to Hytale, and exports a .prefab.json prefab.

The .litematic and .prefab.json formats

A .litematic file is a Litematica schematic — regions of Java block states with placement metadata. A Hytale .prefab.json is Hytale's prefab format: a JSON list of positioned blocks referencing Hytale's block names. The conversion merges the Litematica regions, maps each Minecraft block to its closest Hytale equivalent, and writes a prefab for a Hytale project.

How to convert .litematic to .prefab.json

Upload your .litematic file in the converter below.

Check the Hytale block mapping in the 3D or layer preview.

Keep .prefab.json selected and download the Hytale prefab.

When to use this conversion

Use this route to move a Minecraft Litematica build into a Hytale build or map project as a reusable prefab.

Compatibility notes

Minecraft and Hytale have different block sets, so each block maps to the closest Hytale match and some may have no exact equivalent. Review the preview and the missing-block report before using the prefab.
