FBX Model Viewer

About this format

FBX (Filmbox) is a proprietary 3D format owned by Autodesk and supported by Maya, 3ds Max, MotionBuilder, and Blender. It is the de facto exchange format for rigged characters, animated scenes, and motion-capture data. GLBKit renders .fbx files in the browser so you can review geometry, materials, and textures without installing a DCC tool.

What is a .fbx file?

.fbx is a binary (or ASCII) container that stores geometry, skeletons, animation curves, materials, and cameras in a single file. It is the format most rigged character pipelines use to move assets between tools.

It is proprietary, but the binary format is widely supported by open source tools. GLBKit parses it with a community-maintained loader, so you do not need an Autodesk licence to view a model.

• Stores geometry, skeletons, animation, materials, and cameras
• Binary or ASCII variants, both with the .fbx extension
• Standard exchange format for Maya, 3ds Max, MotionBuilder, Blender
• Widely used for rigged characters, mocap, and game assets

Common uses for FBX files

FBX is the format of choice for character pipelines, mocap, and game-ready assets. Most third-party character stores sell FBX.

• Rigged character and creature pipelines
• Motion capture and animation exchange
• Game-ready character and prop assets (Unity, Unreal, Godot)
• Architectural and product visualisation with animation

How GLBKit renders .fbx files

GLBKit parses the FBX binary and loads its geometry and materials into a Three.js scene. Skeleton joints are not bound for deformation, so rigged characters render as static meshes in the pose stored in the file, and animation clips are listed in the analyzer panel rather than played back.

• Drop a .fbx file to start
• Orbit, pan, and zoom with mouse, touch, or pen
• Animation clips reported by name and duration, without playback
• No upload, no signup, fully local processing

GLBKit capabilities for .fbx

GLBKit focuses on visual inspection. You can confirm geometry, materials, textures, and which animation clips a file contains without round-tripping through a DCC tool.

• Static mesh and material rendering
• Animation clip names and durations via the analyzer panel
• Material and texture rendering from embedded data
• Process files locally in the browser - nothing is uploaded

Who uses GLBKit for .fbx files

Anyone in a character or animation pipeline benefits from a fast, private FBX viewer. GLBKit lets you confirm what is in a file before you commit to a long import.

• Character artists and riggers reviewing exports
• Animators checking mocap and keyframe animation
• Game developers validating third-party FBX assets
• Educators and students learning rigging and animation

How to Open FBX Files Online

Learn how to open, view, and inspect FBX 3D scenes online using the GLBKit FBX Model Viewer.

1. Upload your FBX fileDrag and drop your .fbx file into the viewer or click the upload button to select an FBX file from your device.
2. Load the FBX sceneGLBKit loads the FBX scene and its available resources directly in your browser without requiring desktop software.
3. Navigate the 3D sceneRotate, zoom, and pan the camera to explore the FBX model and inspect different parts of the scene.
4. Inspect FBX resourcesReview supported scene components including meshes, materials, textures, and the animation clips the file contains.
5. Preview the FBX modelUse the browser-based viewer to check your FBX asset before using it in a website, application, or other 3D workflow.
