The difference between a USDC file and a USDZ file lies in their formats and use cases:

  • USDC: This is a binary format. It is efficient for storing large amounts of data, such as geometry, but it cannot be read as plain text. It is suitable for scenarios where performance and storage efficiency are critical.

  • USDZ: This is a zip format. It packages all dependencies for an asset, such as textures, into an internal file structure. This makes USDZ great for publishing and distributing assets. However, they cannot be edited without unzipping.
