Is it possible to convert BBMODEL to GLTF?
Yes - BBMODEL converts to GLTF.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Load the .bbmodel in Blockbench and choose File > Export > Export as glTF, keeping the text .gltf option. You get a standard glTF with its texture, though quads become triangles and vertices are split per face.

Why convert BBMODEL to GLTF?

.bbmodel is the editable Blockbench project, while .gltf is the open, widely supported glTF 2.0 transmission format used by game engines and web 3D viewers. Exporting to .gltf turns a Minecraft-style box model into a standard mesh that three.js, Babylon.js, Godot and Unity can load.

How to convert BBMODEL to GLTF

Blockbench (File > Export as glTF) OPEN-SOURCE

Open the .bbmodel, then run File > Export > Export as glTF and keep the .gltf (text) option. Blockbench writes the .gltf alongside its texture.

Blender (import then export glTF 2.0) FREE

Import an intermediate .obj or .gltf from Blockbench into Blender, then use File > Export > glTF 2.0 (.gltf Separate) to fine-tune materials before writing the final .gltf.

About these formats

A .bbmodel file is the native project file of Blockbench, a free 3D model editor used mainly for Minecraft and other low-poly game models. It is a JSON text file that stores the geometry,…

Quality & what to watch

  • During export Blockbench triangulates quads and no longer shares vertices between faces, so the .gltf mesh is denser than the original box model.
  • A text .gltf usually references its texture and buffer as separate files; keep them together or pick .glb if you need a single self-contained file.
  • .gltf is meant for rendering and interchange, not re-editing - the editable cube structure of the .bbmodel is not recoverable from it.

Frequently asked questions

Should I pick gltf or glb?
Choose .gltf if you want a human-readable file with separate texture, or .glb if you want everything bundled into one binary file.
Does Blockbench export glTF animations?
Animations export only if the source model format supported them; plain block/item geometry exports without animation.
Where does the texture go?
A text .gltf typically writes the texture as a separate image next to it, so move both files together.
Can Unity or Godot open the .gltf?
Yes, glTF 2.0 is natively supported by most modern engines and web 3D libraries.
