the global event will also contain a Display operator. Adding an Empty Flow

also creates a Particle Flow Source icon in the viewports, at the world origin

(0,0,0).

NOTE If an orthogonal viewport is active when you add an Empty Flow to the

system, the software orients the new source icon parallel to the plane of the active

viewport, with the default emission direction pointing forward. For example, if

the Front viewport is active, the icon is oriented parallel to the XZ plane in the

world coordinate system, with the default emission direction along the positive Y

axis. If a Camera or Perspective viewport is active, Particle Flow uses the default

orientation: parallel to the XY plane, pointing in the negative Z direction.

Standard Flow provides a starting point for a particle system consisting of a

global event containing a Render operator, wired to a birth event containing

a Birth, a Position, a Speed, a Rotation, a Shape, and a Display operator, with

all parameters set to default values. This is the same system that the software

creates automatically when you add a Particle Flow icon to the viewport.

To use Standard Flow, drag it from the depot to the event display. In Particle

View, this creates the particle system described above. If the Global default

display option is active in the Particle View > Options menu, the global event

will also contain a Display operator. Adding a Standard Flow also creates a
