drag force field
This field will apply drag, a reduction in linear velocity over time, inside of the drage field shape. 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.

active |
|
Is the Drag field currently active? |
True |
attenuation |
|
Attenuation will reduce the amount of energy of the drag |
