Convertpoly has no write-up on Specifiction yet; its figures are above.

FBX-glTF-conv is a free command-line utility for converting FBX files to glTF, with an output path ending in .gltf or .glb. The project describes it as a component used with Cocos Creator and as an alternative to FBX2glTF for that purpose. Its listed conversion support includes meshes, scene hierarchy, skinning, blend shapes or morph targets, and skeletal node transform and blend shape animations. Supported materials include Lambert and Phong. Textures can use JPEG or PNG images, with options to resolve textures and control image paths. The project lists Windows, macOS, and Linux, and reports testing on Windows, macOS 10.13 or later, and Ubuntu 22.04; Ubuntu 20.04 is unsupported. Additive cluster mode, FBX-specific node inherit types, cameras, and lights are marked unfinished. Building requires Windows or macOS, FBX SDK 2019 or higher, vcpkg, and CMake. The software is under the MIT License, which includes an as-is warranty disclaimer. The repository links to releases and directs users to file an issue for build problems.
