Asset Resolvers

  • URI resolver by Luma Pictures

  • S3 URI resolver Western Digital's S3 asset store resolver

  • RodeoFX resolver RodeoFX's Replace Resolver (last commit: 2019)

  • turret_usd: Animal Logic's URI resolver for turret

  • USD Asset Resolver Reference Implementations (Part of the USD Survival Guide, implement the AR 2.0 spec):

    • File Resolver: A file system based resolver similar to the default resolver with support for custom mapping pairs as well as at runtime modification and refreshing.

    • Python Resolver: Python based implementation of the file resolver. The goal of this resolver is to enable easier RnD by running all resolver and resolver context related methods in Python. It can be used to quickly inspect resolve calls and to setup prototypes of resolvers that can then later be re-written in C++ as it is easier to code database interactions in Python for initial research.

Building

There are a variety of strategies for building USD.

  • Official USD repo The repo includes a robust build script that pulls canonical dependency sources, and can build for all supported platforms.

  • USD Build Club This is the most thorough and flexible method for building USD and all its dependencies for macOS and Windows. Dependencies are fetched from canonical sources.

  • Ubuntu scripts

  • Rez

  • rez-cook Wrapper around rez for one-line builds of USD with any desired dependencies on Windows and Linux

  • USD Superbuild

  • USDPluginExamples A collection of example USD plugins and plugin build tools.

Distros

Engine Integrations

FileFormat plugins

  • usdat DreamWorks usd ASCII format with templates. usdat allows the definition of a common template layer for an asset. Properties and references can be defined at asset install time as part of the reference to that asset when it is added to a scene, rather than using a separate composition arc like an override or a variant.

  • usdStl An STL file format plugin for USD by Charles Flèche

  • usdFBX An FBX file format plugin by Remedy Entertainment. Related blog post: https://www.remedygames.com/northlight-openusd-workflows/
