About This Tool
GLB is the standard for web 3D, but game engines like Unity and Unreal primarily use FBX for asset import. This converter bridges the gap by transforming GLB models into FBX with full support for meshes, materials, textures, bones, and animation clips.

Frequently Asked Questions
Can I import the converted FBX directly into Unity?
Yes. The output FBX file uses standard Autodesk-compatible structure and can be dragged into Unity's Assets folder. Materials and textures are exported separately for Unity's material assignment workflow.
Are PBR materials from GLB converted properly for game engines?
PBR metallic-roughness materials from GLB are mapped to FBX material properties. While FBX uses a different material model, the converter maps base color, metallic, roughness, and normal maps to the closest FBX equivalents for reasonable visual fidelity in engine.
Is the output FBX binary or ASCII format?
The output is always binary FBX, which is recommended for game engines due to smaller file size and faster loading.
How are GLTF KHR material extensions handled?
Common KHR extensions (e.g., KHR_materials_unlit, KHR_materials_clearcoat) are mapped to the closest FBX material properties. Since FBX uses a different material model, some advanced effects may need manual adjustment.
What if the model scale is incorrect after conversion?
GLB/GLTF uses meters, while FBX commonly uses centimeters. Adjust the scale factor in conversion settings (typically set to 100), or modify the import scale factor in your engine after importing.
Which FBX version is the output compatible with?
The output is compatible with FBX 7.x (2011+), correctly recognized by Unity, Unreal Engine, Blender, Maya, and other mainstream software. For older FBX versions, import into Blender first and re-export.
