nParticles are emitted, but they fall through the side of the candy package
and disappear. This is because the nParticles cannot yet collide with any
of the other objects in your scene. For your nParticles to collide with the
candy package and bowl, these meshes need to be passive collision objects
and members of the same Maya Nucleus solver system as the nParticles.
Making nParticles collide with their environment
In the second step of creating an nParticle effect, you convert the meshes you
want the nParticles to collide with to passive collision objects. When nParticles
collide with passive collision objects, their behavior, speed, and direction
change. Passive collision objects are not affected by collisions with other
objects.
In this lesson, you convert the candy package, bowl, and the desk surface
geometry to passive collision objects. The nParticles can then collide with
these objects.
To convert geometry to passive collision objects
1 Rewind the simulation to the start frame.
2 In the scene view, Shift-select the package and bowl meshes as well as
the surface of the desk.
3 Select nMesh > Create Passive Collider > .
