Refining Scenegraph Instances

In this lesson, you’ll learn various techniques for refining scenegraph instances to introduce variety and customization while maintaining performance benefits. Here’s what we’ll accomplish:

Learning Objectives

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

• Understand the fundamental rules of instance editability and why they exist

• Apply different refinement techniques including deinstancing, refinement using variant sets, and hierarchical refinement

• Evaluate the performance impact of each refinement approach using stage statistics

• Choose the most appropriate refinement technique for specific use cases

• Implement complex refinement workflows that balance performance with authoring flexibility
