You can generate a force field from your nParticle object that either pushes nCloth objects or other nParticle objects away from your nParticles, or pulls nCloth objects or other nParticle toward your nParticles. Force fields generated by nParticle objects are similar to the force fields generated by nCloth, but nParticles generate forces from the individual particles or points of the nParticle object. This force is termed a Point Force Field. A Point Force Field is defined by the magnitude of the force field as well as Point Field Distance, which is the distance from the field generating object that the field is active. Positive Point Field Magnitude values produce a force that push Nucleus objects away, while negative Point Field Magnitude values generate a force that pulls objects towards the nParticles. The active area or region of the force field is defined by a Point Field Distance attribute. You can use the Point Field Scale ramp to control how Point Field Magnitude is distributed along the area defined by Point Field Distance.
nParticle objects can also generate a Self Attract force. By adjusting Self Attract, an nParticle object’s individual particles can be made to attract or repel each other.
