USD vs FBX
USD is a scene-description foundation for composing multiple assets, while FBX is widely used to exchange 3D production data. Their fit depends on the pipeline and on what the receiving tools preserve.
Which format should you choose?
Consider USD for layered, non-destructive scene assembly and FBX for exchanging individual production assets in established tool workflows.
Good fit for USD
Large 3D production pipelines
- Combining referenced assets and variants across a 3D production team
Good fit for FBX
3D production handoff
- Passing rigged characters and animation between compatible creation tools

| How to open | Open in a USD-capable DCC tool or viewer and inspect layers, assets, materials, and animation. | Open in an FBX-capable editor or viewer and inspect meshes, materials, textures, scale, rigs, and animation. |
| Export or convert | When converting to glTF or FBX, check scene composition, variants, materials, and animation. | When converting to glTF, verify materials, texture links, animation, units, and axis orientation. |

FBXKey point 1
USD can compose scenes through layers, references, and overrides.
More on the differencesKey point 2
FBX is commonly used to transfer 3D assets among content-creation applications; support can vary by application.
More on the differencesMore on the differences
Use USD when collaborative scene composition and reusable references are central. Choose FBX when the target applications already have a reliable FBX handoff. Test geometry, materials, rigs, animation, units, and transforms in both directions.
- USD's composition model supports layers and references for assembling scenes.
- FBX interoperability is common but feature handling differs across importers and exporters.
- Neither guarantees identical results across every tool; validate the actual exchange path.
Frequently asked questions
Which is better for animation, USD or FBX?
It depends on the applications and animation features in the pipeline; test a representative scene through the exact import and export steps.
