Authoring Scenegraph Instancing

In this lesson, you’ll learn how to create and manage scenegraph instances in USD, including enabling instancing and implementing nested instancing hierarchies. Here’s what we’ll accomplish:

Learning Objectives

By the end of this lesson, you’ll be able to:

• Explain how scenegraph instancing works in USD and its relationship to the composition system

• Create scenegraph instances by enabling the instanceable metadata on prims

• Analyze stage statistics to understand the performance impact of instancing

• Implement nested instancing hierarchies for complex scene structures

• Compare the trade-offs between instancing performance and authoring flexibility
