How do I load the structure in game?

Place the .nbt in your world's generated/minecraft/structures folder or in a datapack, then read it with a structure block set to Load.

The model is bigger than 48 blocks per axis.

Use the chunked NBT export. It writes several .nbt files named by their origin coordinates into a zip, so you can place them next to each other and rebuild the whole model.

Do the model's textures carry over?

Yes. A .glb embeds its textures, so the voxelizer samples them and matches each surface colour to the nearest block in your palette.

Does this work on a vanilla server?

Yes. Structure blocks and datapack structures are vanilla features, so no mods or plugins are needed.

Convert .glb to .nbt

Turn a textured 3D model into a vanilla Minecraft structure. Because a .glb bundles its own textures, Bloxelizer can sample the model's real colours while voxelizing and export a structure-block .nbt that needs no mods.

The .glb and .nbt formats

.glb is the binary form of glTF: one self-contained file holding geometry, node transforms, PBR materials, and embedded textures — the standard export from Blender and Sketchfab. A structure-block .nbt is Minecraft Java Edition's native format: a block-state palette, positioned blocks, and a data version, read in-game by a structure block that caps at 48 blocks per axis. The conversion voxelizes the mesh, samples its embedded textures for colour, and writes the result as a vanilla structure.

How to convert .glb to .nbt

Upload your .glb file in the converter below.

Set the build size, palette, and pose in the preview panel, then apply.

Leave .nbt selected as the export format and download the structure.

When to use this conversion

The route to take when a downloaded or sculpted model has to end up in unmodded Java Edition — a datapack, an adventure map, or custom world generation that reads .nbt structures.

Compatibility notes

Structure blocks read at most 48 blocks per axis; for larger models use the chunked NBT export, which splits the build into origin-named .nbt files in a zip. Rigged models are baked into a single pose before voxelization — pick that pose in the preview panel.
