The KatanaUsdPlugins were originally authored by Pixar and this repository was originally based on the 19.11 version of the USD library. https://github.com/PixarAnimationStudios/USD/releases/tag/v19.11
This section contains libraries and plug-ins for Katana. We have provided a new build mechanism to modularize the building process, allowing the plug-ins to be built against multiple compatible USD and Katana versions (depending on API compatibility). There is a document attached to this repository (BUILDING.md) which describes how to go about making your own CMake build scripts.
See the online documentation for more details.
