Universal Scene Description (USD) is a standard 3D format created by Pixar. It is the backbone of Omniverse and it’s something that you are bound to encounter when programming within in the Omniverse ecosystem. USD usually comes into play when you need to manipulate a Stage in some way, such as accessing or modifying Prims.
