direction force field
This field will move particles in a direction based on the direction field shape position, rotation and scale. Particles outside of the field will not be affected. 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.
