Source format: USD
USD usually refers to Universal Scene Description, a 3D scene description format developed by Pixar and widely used in animation, visual effects, game production, and digital content creation. It can store complex scene data such as geometry, materials, transforms, animation, and references to other assets. USD is commonly used in pipelines that need non-destructive scene assembly and collaboration across multiple tools.
Target format: USDC
USDC is the binary, crate-based variant of Universal Scene Description. It stores the same kind of scene data as USD, but in a compact binary form. Compared with plain-text USD files, USDC is typically smaller, faster to load, and better suited for large production scenes. It is widely used when performance and storage efficiency matter.
How to perform the conversion
The most reliable way to convert USD to USDC is with the official Pixar USD tools, especially usdcat. This tool can read a text-based USD file and write it out as a binary USDC file.
- Install the Pixar USD tools on your system. They are available as part of the USD distribution and are also included in some DCC applications and pipeline toolsets.
- Open a terminal or command prompt.
- Run a command like
usdcat input.usd -o output.usdc. - Verify that
output.usdcopens correctly in your 3D application or USD viewer.
If your USD file is already part of a larger asset structure, make sure any referenced files, textures, and payloads remain in the expected relative paths after conversion. In many cases, the conversion only changes the file encoding, not the scene content.
You can also convert the file on 101convert.com for free, without installing any software.
Notes on quality, compatibility, or limitations
USD and USDC contain the same scene information; the conversion is generally lossless when the source file is valid. The main differences are storage format and performance, not visual quality.
Keep in mind that:
- USDC is not human-readable, so it is harder to inspect or edit manually than text USD.
- Some pipelines prefer text USD for version control and code review, while others prefer USDC for speed and smaller file size.
- If the source USD file contains references to external assets, those references are preserved, but the referenced files themselves are not converted automatically.
- Compatibility depends on the USD version supported by your software; very old tools may not open newer USD/USDC files correctly.
