Modify particle system parameters in the HUD
Adjust particles from the HUD in Motion
When you create an emitter, the particle system begins working according to the default
parameters in its Emitter Inspector and Particle Cell Inspector. You can modify the most
important of these parameters in the Emitter HUD.
Display an Emitter HUD
In Motion, select the emitter in the Layers list, Timeline, or canvas.
The Emitter HUD appears. (If it does not appear, click the HUD button in the toolbar or
press F7.)
Adjust parameters for a 2D emitter in the Emitter HUD
In the Emitter HUD in Motion, do any of the following:
Drag a slider:
Birth Rate: Sets how many particles are created every second.
Life: Sets how long each particle remains onscreen (in seconds) before disappearing
from existence.
Scale: Sets the size of each particle, relative to the original size of the cell.
Emission Range: Sets the angle at which particles are emitted.
Drag in the graphical emission control to modify several parameters simultaneously:
Emission Range, Emission Angle, and Emission Speed. See Emitter HUD controls in
Motion.
