Create a Component to Component constraint to attach nParticle objects to other nParticle objects or to nCloth or passive object components.
For example, you can constrain nParticles to the vertices of a character’s nCloth shirt, so that the nParticles cling to the shirt as it moves with the character.
To create an nParticle Component to Component constraint
If you select target components on a non-nCloth object, that object will be made a passive object when the constraint is created.
The nParticle object is now constrained to the other target nParticle object or to the target vertices of the nCloth or passive objects you selected, and they are now connected to the nParticle object’s Maya Nucleus solver through a dynamicConstraint node.
The preset properties on the dynamicConstraint node determine the constraint’s type (in this case, a Component to Component constraint) and how it behaves. For example, you can create a Component to Component constraint with the following attribute settings:
