OpenUSD
OpenUSD, or Universal Scene Description, is an open-source system for describing, composing and exchanging 3D scenes. Artists can combine geometry, materials and lighting while retaining layers and variants for further work. In a digital-fashion workflow, a colourway variant and a campaign-lighting revision can remain distinct contributions to the scene. That is a possible use of USD's composition model, rather than evidence that a particular garment application supports the whole workflow. Export support alone does not establish which shaders or animation will survive a handoff. The production team needs an agreed supported subset and a review of the scene in the receiving application.

What to check
- Check that the receiving environment can resolve all referenced assets and files.
- Retain the variants and layer structure that the next artist needs, rather than assuming a flattened delivery remains editable.
- USD is not a rigging system. A USD export does not by itself preserve a garment application's rig or simulation.
