My .gltf will not load — why?

Most likely it references external .bin or texture files, which are not read alongside it. Re-export from your 3D tool as embedded glTF or as .glb, both of which are self-contained.

What is the difference between .gltf and .glb?

They describe the same scene. .gltf is JSON and can point at external files; .glb packs everything into one binary. For this converter, .glb is the safer choice.

Are the model's materials used to pick blocks?

Yes. Base colours and embedded textures are sampled during voxelization and matched against the selected palette.

Can WorldEdit paste the result?

Yes. The output is a Sponge .schem, read by WorldEdit 7 and newer as well as FAWE.

Convert .gltf to .schem

Turn a glTF scene into a Minecraft build. Bloxelizer parses the .gltf in your browser, voxelizes it at the size you choose, and exports a WorldEdit-compatible .schem.

The .gltf and .schem formats

.gltf is the JSON form of glTF — a scene description of meshes, node transforms, and PBR materials, where buffers and textures are either embedded as data URIs or stored as separate .bin and image files next to it. A Sponge .schem is gzipped NBT holding namespaced Minecraft block states for WorldEdit and FAWE. The conversion voxelizes the mesh onto a block grid and matches each sampled surface colour to the nearest block in your palette.

How to convert .gltf to .schem

Upload your .gltf file in the converter below — embedded rather than one referencing external .bin files.

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

Leave .schem selected as the export format and download the schematic.

When to use this conversion

Use this route when your 3D tool exported JSON glTF rather than a binary .glb, and you want the model as a schematic you can paste with WorldEdit or FAWE.

Compatibility notes

Use a self-contained .gltf — one with its buffers and textures embedded. A .gltf that references external .bin or image files will not resolve them, so re-export it as embedded glTF or as .glb if the model fails to load.
