Particle Formation group
These options let you specify the shape of the emitter.
Box Emitter Chooses a box-shaped emitter.
Sphere Emitter Chooses a sphere-shaped emitter.
Cylinder Emitter Chooses a cylindrical emitter.
Object-Based Emitter Chooses the object selected in the Object-Based Emitter
group.
NOTE With regard to animation of the object-based emitter, the particles will
properly fill a deformed object at frame 0, but they can't stay with the emitter
while it's moving. If the emitter moves in a straight line, this can give the
appearance of the cloud moving with the emitter.
Display Icon group
These options let you adjust the dimensions of the emitter icon when a custom
object is not used as an emitter. When a custom object is used you can still
resize the "Fill" icon using these options.
Rad/Len Adjusts the radius of a spherical or cylindrical icon, and the length
of a box icon.
Width Sets the width of a box emitter.
Height Sets the height of a box or cylindrical emitter.
Emitter Hidden Hides the emitter.
