Which programs open a .glb file?

GLB is the binary GLTF format read by Blender, three.js, Windows 3D Viewer, and most modern 3D and game engines.

Does the .nbt need to be a structure file?

Yes. This converter expects a Java Edition structure file, such as one saved by a structure block, rather than arbitrary NBT data.

Are block textures kept in the model?

Yes. The textures are embedded in the .glb so it renders like the in-game structure.

Does redstone or command data export?

No. A 3D model only contains geometry and textures, not functional block data.

Convert .nbt to .glb

Turn a Java Edition structure block .nbt build into a standalone 3D model. Bloxelizer reads the structure, renders the blocks with their textures, and exports a .glb model for Blender, three.js, or any GLTF-compatible tool.

The .nbt and .glb formats

A structure-block .nbt file is Minecraft's own block data — a palette and positioned blocks — not a mesh. The .glb format is binary glTF 2.0 with geometry and embedded textures. The conversion renders the structure's blocks into a textured model for use in Blender, three.js, or a 3D-printing workflow.

How to convert .nbt to .glb

Upload your Java structure .nbt file in the converter below.

Inspect the build in the 3D preview.

Select .glb as the export format and download the 3D model.

When to use this conversion

Use this route to render a vanilla structure outside Minecraft, import it into a game engine or animation, or prepare it for 3D printing.

Compatibility notes

The GLB captures the structure's blocks and textures as geometry. Redstone behavior, entities, and in-game interactivity are not part of a 3D model export.
