radial force field

Creates a radial collision field effect on particles. 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 Radial field currently active?

True

attenuation

float

Attenuation of the radial field. Attenuation is how much the effect of the field decays from the ‘center’ to the ‘boundary’ of the Noise Field Source.

1.0

magnitude

float

Magnitude of the radial field. The amount of force to apply to the particles on the radial field.

1.0

pointcloudPoints

pointf[3][]

Input pointcloud points

[]

pointcloudNormals

normalf[3][]

Input pointcloud normals, one for each point

[]

pointcloudPointRadius

float

radius of points in cloud

1.0
