Create menu > Particles > PCloud
Use the PCloud (or Particle Cloud) particle system when you want a "cloud"
of particles that fill a specific volume. PCloud can provide a flock of birds, a
starfield, or a troupe of soldiers marching over terrain. You can confine the
particles using basic supplied volumes of a box, sphere, or cylinder, or you
can use any renderable object in the scene as a volume as long as that object
has depth. Two-dimensional objects do not work with PCloud.
