Emitter controls in Motion
The parameters in the Emitter Controls section of the Emitter Inspector determine how
particles are distributed and rendered in your project.
Several of these controls are identical to those found in the Emitter HUD, with one
difference: Although the emission control in the Emitter HUD lets you manipulate the Range,
Angle, Latitude (3D), Longitude (3D), and Speed parameters using a single graphical
control, the Emitter Inspector uses individual numeric controls for each parameter.
Note: The settings for emitters in the Properties Inspector and Emitter Inspector can be
keyframed to change values over time. However, there’s no way to control the animation of
individual particles.
Some parameters in the Emitter Inspector depend on the settings of other parameters. All
combinations of parameters are described below:
Shape: A pop-up menu to set the overall shape of the emitter. Different shapes
significantly alter the distribution of generated particles. When you choose an emitter
shape, different Emitter Inspector parameters appear that are unique to that shape.
For example, when Rectangle is the selected shape, Outline, Tile Fill, and Random Fill
become available in the Arrangement options.
The Shape pop-up menu contains the following items:
Point: The default shape for new emitters, specifies a single point of emission for a
particle system.
