FBX-glTF-conv

FBX-glTF-conv is a free command-line converter for moving FBX assets into glTF or GLB files. It is best suited to developers and technical artists building scripted pipelines, especially around Cocos Creator. Its focused support for meshes, materials, textures, skinning, and animation is useful, but unfinished scene features limit it as a universal interchange tool.

Overview

The program runs as an executable that accepts an FBX input path and a glTF output path. You can choose a .gltf or .glb destination, which makes it a natural fit for repeatable, terminal-driven processing rather than occasional desktop conversion. The project is intended essentially as part of Cocos Creator and was created as an alternative to FBX2glTF for that workflow.

That narrow purpose is important when choosing it. A Cocos-oriented pipeline can use the converter without a paid account, subscription, or stated usage quota. A project that depends on complete FBX scene coverage should look elsewhere: additive cluster mode, FBX-specific node inherit types, cameras, and lights are marked unfinished.

Key features

Meshes, materials, and textures

Mesh conversion covers the central geometry task, while Lambert and Phong materials support the material types named by the project. JPEG and PNG images are supported, with options to resolve textures and control their paths. This combination suits game assets built around standard image textures and conventional shading; it does not promise coverage for material or scene constructs outside that stated scope.

Animation and scene data

The feature set includes skeletal node-transform animation and blend-shape animation, along with skinning, blend shapes (morph targets), and scene hierarchy. That is a meaningful base for characters and deforming assets: skeletal motion and morph-driven facial or shape changes can travel with the model. The unfinished camera, light, inherit-type, and additive-cluster work means cinematic or technically complex FBX scenes may need another converter or follow-up processing.

Command-line workflow

Because input and output are supplied as paths to an executable, the tool is oriented toward build scripts and asset pipelines. It is a good match for teams that already automate conversion and a poor fit for users expecting a graphical batch queue or visual scene inspection.

Pricing

The free plan is the entire commercial offering described: software under the MIT License, with no paid tier or stated conversion cap. It suits personal, commercial, and pipeline use where the license and command-line model fit. The MIT license includes an as-is warranty disclaimer, so teams remain responsible for evaluating the converter in their own production process.

Platforms

FBX-glTF-conv supports Windows, macOS, and Linux. The project says it has been tested on Windows, macOS 10.13 or later, and Ubuntu 22.04; Ubuntu 20.04 is unsupported. Building is a separate consideration: the requirements include Windows or macOS, FBX SDK 2019 or higher, vcpkg, and CMake. Users who only need a released executable may avoid that build work, while organizations compiling their own version should budget for those dependencies. Build problems are directed to the project's issue tracker, and the releases page lists version 1.0.0-alpha.54.

Who it's for

This is for Cocos Creator developers, technical artists, and pipeline engineers who need deterministic FBX-to-glTF conversion in scripts and whose assets center on meshes, standard materials, textures, skinning, and skeletal or blend-shape animation. It is less appropriate for artists wanting a graphical converter, for Ubuntu 20.04 deployments, or for productions whose FBX files rely heavily on cameras, lights, additive clusters, or FBX-specific node inheritance.

Pros and cons

• Pros: Free MIT-licensed distribution removes subscription and usage-cost concerns.
• Pros: glTF and GLB output, texture-path controls, skinning, morph targets, hierarchy, and two animation categories cover a useful game-asset pipeline.
• Pros: Windows, macOS, and Linux support broadens deployment options.
• Cons: Cameras, lights, additive cluster mode, and FBX-specific inherit types remain unfinished.
• Cons: Building requires the FBX SDK 2019 or newer plus vcpkg and CMake, and Ubuntu 20.04 is unsupported.

Alternatives

Choose HOOPS Exchange instead when you need broad platform coverage and a paid evaluation with full access, 60 days, and technical expert support. CAD Assistant is a free cross-platform option for personal and commercial use, though commercial import components restrict model export and conversion.

Open Asset Import Library (Assimp) suits developers wanting a free, self-hostable library under a modified three-clause BSD license. Convert3D is preferable when an API and defined quotas matter: its free tier allows 10 conversions per month, with paid annual tiers available. ODA File Converter is another free option for CAD-focused workflows. Spin 3D offers a free version for non-commercial use on macOS, web, and Windows. meshio is a free MIT-licensed choice for mesh conversion, with NumPy at its core and optional dependencies for some formats.

Verdict

Choose FBX-glTF-conv if you need a free, scriptable FBX-to-glTF/GLB step for Cocos Creator or a similar asset pipeline and your content fits its supported geometry, texture, skinning, and animation model. Look elsewhere when you need finished camera and light conversion, broader FBX scene fidelity, a graphical interface, or a build environment that cannot meet its SDK and operating-system requirements.
