About

Pixar maintains documents the official list of USD 3rd party library compatibility matrix tested before a USD release here:

https://github.com/PixarAnimationStudios/USD/blob/release/VERSIONS.md

This wiki tracks the unofficial compatibility of USD with the VFX reference platform, vendor integrations, and other versions of 3rd party libraries, as reported by the USD community. Pixar does not endorse any compatibility listed here, and the build tools that ship with USD may not directly support building USD with alternate dependencies and requirements. That said, studios have had success using USD in the configurations reported below.

Compatibility charts use these symbols to denote likely compatibility.

	Compatible, verified in production
	Partially compatible, or customizations required to obtain compatibility - see footnotes for details
	Verified not compatible
	No compatibility reports yet

VFX Reference Platform Compatibility

About the VFX Reference Platform:

The VFX Reference Platform is a set of tool and library versions to be used as a common target platform for building software for the VFX industry. Its purpose is to minimise incompatibilities between different software packages, ease the support burden for Linux-based pipelines and encourage further adoption of Linux by software vendors. The Reference Platform is updated annually by a group of software vendors in collaboration with the Visual Effects Society Technology Committee.

The table below lists which USD versions have been built with dependencies specified by the various VFX reference platforms and used in production.  

VFX Platform / USD compatibility

	21.02	20.11	20.08	20.05	20.02	19.11
VFX-2021
VFX-2020
VFX-2019
VFX-2018
VFX-2017				1
VFX-2016				1,2

¹ 20.05 introduced C++14 as a build requirement, but minor changes to vt/dictionary can enable C++11 support for a small performance penalty

2 20.05 moved the Alembic requirement to 1.7, but minor changes to usdAbc allow earlier versions to be supported

DCC Compatibility

Maya

Maya supports USD primarily through the open-source USD for Maya plugin:

https://area.autodesk.com/blogs/the-maya-blog/maya-usd/

https://github.com/Autodesk/maya-usd

Future versions of Maya will ship with this plugin and USD built in, although studios will still be able to substitute their own builds of the plugin and USD in place of the versions shipped with Maya.

USD for Maya plugin / Maya compatibility

	Maya 2020	Maya 2019	Maya 2018
USD for Maya 0.7
USD for Maya 0.6
USD for Maya 0.5			1
USD for Maya 0.4			1
USD for Maya 0.3			1

¹ UFE (Universal Front End) is only available starting in Maya 2019. The USD plugin will build for Maya 2018 with reduced functionality.

Houdini

Houdini supports USD through its Solaris toolset:

	21.02	20.11	20.08	20.05	20.02	19.11
Houdini 18.5
Houdini 18.0

Solaris and USD are shipped as part of Houdini. Studios may choose to replace the internals of Solaris with a version they build themselves, using their internal builds of USD, by building the HoudiniUsdBridge provided by SideFX:

https://github.com/sideeffects/HoudiniUsdBridge

	21.02	20.11	20.08	20.05	20.02	19.11
Houdini 18.5+HoudiniUsdBridge
Houdini 18.0+HoudiniUsdBridge			1,2	1,2	1

¹ Requires modifications to HoudiniUsdBridge

² Requires modifications to HoudiniUsdBridge, Houdini Python modules (not delivered with HoudiniUsdBridge), some functionality reduced 

Unity

Unity supports USD through its open-source com.unity.formats.usd package:

https://docs.unity3d.com/Packages/com.unity.formats.usd@1.0/manual/index.html

https://github.com/Unity-Technologies/usd-unity-sdk

The package works with Unity versions 2018.4 and up.
