Particles

Overview

Warning

ATTENTION!: omni.particle.system.core is currently undergoing extensive changes. Please be aware that systems built with the existing extension will need to be rebuilt in the USD Composer 2023.2 release.

The Particle System is a set of operators implemented as OmniGraph nodes and other tools for simulating and rendering of particle effects. This page contains documentation for the Particle System including a Getting Started, a User Interface and Tutorials.
