LIVERPS Strenth Ordering#

A Note About LIVERPS vs LIVRPS

OpenUSD recently introduced a new composition arc called “relocates,” which is now included in the strength ordering acronym. What was previously known as LIVRPS is now LIVERPS, with the “E” representing rElocates. Learn OpenUSD will be updated soon to cover relocates, but for now, please note that you may see both LIVRPS and LIVERPS used interchangeably.

Let’s continue with the last lesson in this module, LIVERPS Strength Ordering. LIVERPS is a fundamental concept in USD that governs how different composition arcs are applied when creating a scene. This knowledge is key to understanding how USD resolves conflicts in opinions and determines the final state of a scene when multiple layers and composition operations are involved.

In this module, we will:

  • Understand the meaning of the LIVERPS acronym.

  • Learn about the hierarchy of composition arcs and their relative strengths.

  • Explore the concept of layer stacks and how they relate to LIVERPS.

  • Gain insight into how LIVERPS determines the composition of prims and properties on a USD stage.
