What is a .USD file?
USD (Universal Scene Description) is a powerful 3D scene format used across film and 3D pipelines. Created by Pixar.
- Did you know
- Pixar created USD for its own films and open-sourced it in 2016; it now anchors NVIDIA’s Omniverse.
- USD grew out of Pixar’s in-house Presto animation system, whose layering and referencing ideas were extracted into a reusable scene format from 2012.
- A .usd layer may be stored as either text or binary, and references stay valid when you switch between the two without rewriting the scene.
- What Analyser reads
- Identify 3D and 3D-printing files: FBX, glTF/GLB, USD/USDZ, and Blender (BLEND). OBJ, PLY, OFF, 3MF and AMF get a full 3D viewer - see the 3D model section.
- Depth of analysis
- .USD is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .USD file
- Drag a .USD file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
