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.

Inputs

Name	Type	Description	Default
active	bool	Is the Drag field currently active?	True
attenuation	float	Attenuation will reduce the amount of energy of the drag	1.0
magnitude	float	The amount of force to apply to the drag. The higher the value, the faster the drag will apply.	1.0
