What FBX2glTF is

FBX2glTF is a command-line tool that converts Autodesk FBX 3D assets to glTF 2.0. It can produce a glTF representation or a single binary .glb file, and can embed buffers as data URIs. Precompiled binaries are provided for Windows, Mac OS X and Linux. The npm package exposes a Promise-based Node API and includes platform binaries. FBX animations are baked into the output, and blend shapes are supported; complex rigs can produce large files. Material conversion includes metallic-roughness PBR support for Stingray PBS, as well as automatic transfer of emissive constants and textures, occlusion maps and normal maps. Optional Draco compression can reduce mesh size, but a viewer must support KHR_draco_geometry_compression. The project is free under a 3-clause BSD license. Its build system supports FBX SDK version 2019.2 only. The initial v0.9.0 release was marked beta because it had not been exposed to a wide variety of FBX variations. The project encourages users to report unexpected behavior or crashes through GitHub issues.

Convert FBX assets to glTF, .glb or embedded-buffer output.

Verdict

FBX2glTF offers multiple output forms, animation conversion and material handling in a free command-line package. Check the SDK restriction and potential animation file size against your workflow.

Questions

How much does FBX2glTF cost?

The Open source plan is free under the 3-clause BSD license.

Which platforms does it support?

Precompiled binaries are provided for Windows, Mac OS X and Linux. The npm package includes binaries for Darwin, Linux and Windows_NT.

What output formats can it create?

It can produce a separate glTF representation, one binary .glb file, or embed buffers as data URIs.

Does FBX2glTF convert animation and materials?

It bakes FBX animations into glTF and supports blend shapes. Material features include metallic-roughness PBR conversion for Stingray PBS and automatic transfer of emissive data, occlusion maps and normal maps.

Is FBX2glTF open source?

Yes. It is licensed under the 3-clause BSD license.

Which FBX SDK version is supported for builds?
