simulation space

This node can specify transformation space for the simulated particles, defined by an Xform prim in the USD stage. Similar to how child-parent transforms work, the particles will conform to the transformations applied the Xform prim. Translation, rotation and scale can be toggled on/off individually. ATTENTION!: omni.particle.system.core is currently undergoing extensive (breaking) changes. Please be aware that systems built with the existing extension will need to be rebuilt in the USD Composer 2023.2 release.

Installation

To use this Node, you must enable omni.particle.system.core in the Extension Manager.
