A Quick Look at USD, Without the Full OpenUSD Stack
Pixar's USD format is built for large, composed production scenes, and the full toolchain to work with it is heavy to install just for a look. GLBKit opens USD and USDA files in the browser to inspect geometry, materials and supported referenced textures — it's an inspection viewer, and it doesn't run full USD composition, variant sets or payload resolution.
USDZ and USDC Aware
Loads supported USD variants along with their referenced texture assets, where available.
Inspect Materials and Textures
Check geometry and shading assignments on a USD or USDA file directly.
No Pixar Tools Required
Get a look at a USD asset without installing the full OpenUSD toolchain.
WebGL Rendering
Renders USD geometry with GPU acceleration in the browser.
Inspection, Not Full Composition
This is a viewer for a quick look — it doesn't run full USD composition, variant sets or payload resolution.
Local Only

About this format
USD (Universal Scene Description) is Pixar's open format for interchange, collaboration, and large-scale scene composition. It is the standard in VFX, feature animation, and architectural visualisation. GLBKit renders .usd and .usda files in the browser, including textures and basic scene structure, so you can review assets and references before opening DCC tools.
What is a .usd file?
.usd is the binary form of Universal Scene Description, a layered, hierarchical format developed by Pixar. It supports geometry, materials, animation, lighting, and complex composition with variants, references, and payloads.
The text form, .usda, is human-readable and great for debugging. The zipped container, .usdz, bundles assets for AR Quick Look on iOS.
- Layered scene description with references and variants
- Binary .usd and text .usda variants, plus .usdz for AR
- Standard interchange format in VFX and feature animation
- Open source, used by Pixar, Apple, NVIDIA, Autodesk
Common uses for USD files
USD is the lingua franca of modern VFX and animation. It is also used in product visualisation, AR, and large-scale scene composition.
- VFX and feature animation pipelines (Pixar, Disney, ILM, DNEG)
- Product configurators and architectural visualisation
- AR Quick Look assets for iOS (via .usdz)
- OpenUSD-based collaboration with Omniverse, Houdini, Maya
How GLBKit renders .usd files
GLBKit parses the .usd file in the browser and renders its geometry, materials, and textures with WebGL. The viewer focuses on visual inspection: geometry, materials, and basic scene structure.
- Drop a .usd or .usda file to start
- Orbit, pan, and zoom with mouse, touch, or pen
- Material and texture rendering where present
- No upload, no signup, fully local processing
GLBKit capabilities for .usd
GLBKit renders the geometry and surface appearance of a USD scene. It does not run full OpenUSD composition, but it gives you a fast, accurate preview of what is in the file.
- Geometry, mesh, and material rendering
- Texture support from referenced image files
- Inspect variants and basic structure
- Process files locally in the browser
Who uses GLBKit for .usd files
USD is everywhere in VFX and animation. GLBKit is the fastest way to confirm what is in a .usd file without opening Houdini or Maya.
- VFX and animation artists reviewing assets
- Architects and product designers previewing USD scenes
- AR/VR developers inspecting .usdz bundles
- Pipeline engineers debugging USD composition
