# USD format

## Universal Scene Description (USD) format

The USD format has been added for import and export. The USD format was developed by Pixar to provide a way to handle scenes made up of many different elements as well as allow multiple artists to collaborate on the different assets.

**Important!**

Note: the USD Format plugin in ZBrush only allows the import and export of meshes rather than whole scenes. The MacOS version will only work on MacOS 10.12 and above.
