Super GLB Viewer for VS Code
View GLB and GLTF 3D model files directly in VS Code — powered by a multi-engine viewer supporting Unity, Three.js, Babylon.js, and PlayCanvas.
Features
- Open GLB/GLTF files directly in VS Code as a custom editor
- Multiple rendering engines — switch between Unity, Three.js, Babylon.js, and PlayCanvas
- WebGL2 and WebGPU backends
- Animations — play/pause, seek, track selection, and speed control
- Blend shapes / morph targets with adjustable weights
- Inspector — browse the scene graph, edit materials (PBR, clearcoat, transmission, sheen, volume), transforms, and lights
- Model comparison — split view with synchronized camera and stat deltas
- Optimization — mesh compression and KTX2 texture compression
- Export — download your model (including edits) as GLB
- Share — generate a shareable link to your model
- Environment lighting — load custom HDR files, adjust exposure and tonemapping
- Stats panel — vertices, triangles, meshes, materials, textures, and VRAM usage
- Fully offline — all processing happens locally, no data leaves your machine (except when using the Share feature, which uploads your model to generate a link)
