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

Description |
Default |
---|---|---|---|
active |
|
Is the Radial field currently active? |
True |
attenuation |
|
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 |
|
Magnitude of the radial field. The amount of force to apply to the particles on the radial field. |
