central logo (see above illustration), but you can change its shape and
appearance using the controls described below.
When you select a source icon in the viewport, the Particle Flow emitter-level
rollouts appear on the Modify panel. Alternatively, click the title bar of a global
event in Particle View to highlight it, and to access the emitter-level rollouts
from the parameters panel on the right side of the Particle View dialog. Use
these controls for setting global attributes, such as icon properties and the
maximum amount of particles in the flow.
The particle source icon is roughly equivalent to the corresponding
global
event
on page 7997 in Particle View. They have the same name, but selecting
one does not select the other. If you delete a particle source icon from the
scene, the software converts the global event to an isolated local event in
Particle View, retaining its operators with their settings intact. Any other
events in the system remain in Particle View, along with their wiring. However,
if you delete a global event, the software also removes any local events used
exclusively by that system, as well as the corresponding particle source icon.
To retain the local events, first delete the wire from the global event, and then
delete the global event.
If you clone a particle source in a viewport with Shift+transform or Edit menu
> Clone, an equal number of copies of the global event appear in Particle View,
each wired to the original
birth event on page 7924. The Clone Options dialog
offers only the Copy option. However, if you clone a global event in Particle
View, the Clone Options dialog also lets you create instances of the cloned
operators and tests. It's not possible to create instances of global and local
events, so these options are unavailable in the Clone Options dialog, as a
reminder. Also, global events cloned in Particle View are not automatically
wired to the original birth event.

Modifier stack
In the modifier stack, expanding the hierarchy of a Particle Flow source object
provides access to two sub-object levels: Particle and Event. For further
information, see
Selection rollout on page 2833.
