Create an nParticle Slide on Surface constraint
Create a Slide on Surface constraint to attach an nParticle object to a target surface (an nCloth surface, or a passive collision object), and allow the constrained nParticles to move or slip along the surface to which it is constrained.
Create an nParticle Force Field Constraint
Create a Force Field constraint to push nParticle objects away from the center of the constraint in a radial field with spherical volume bounds.
Create an nParticle Disable Collision constraint
Create a Disable Collision constraint for an nParticle object to prevent it from colliding with all other Nucleus objects, or Nucleus object vertices.
Create an nParticle Exclude Collide Pairs constraint
Create an Exclude Collide Pairs constraint for nParticle objects to prevent them from colliding with specific nParticle, nCloth, passive objects, or Nucleus object vertices.
Edit nParticle constraint membership
Add, remove, or replace the components that are used in your nParticle constraint by editing constraint membership.
