What is a .USDA file?
USDA is the human-readable text form of Pixar’s USD scene format.
- Did you know
- In 2023 Pixar joined Adobe, Apple, Autodesk and NVIDIA to form the Alliance for OpenUSD, charged with turning the format into a formal open standard.
- USDA is the human-readable text encoding of USD, handy for hand-editing or inspecting a scene, where USDC is the faster binary equivalent.
- USD itself is roughly Pixar’s fourth generation of composed scene description, tracing back to the single linear program files used on the first Toy Story.
- 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
- .USDA 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 .USDA file
- Drag a .USDA 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.
