Chapter 8 Working With Particles 601
• Original: Particles are generated using their original colors. When Original is chosen,
the Opacity Over Life parameter appears. This parameter is a gradient control that
allows you to animate changes to the opacity of particles over their lifetime.
• Colorize: Particles are tinted using the color specified in the Color parameter.
Additional Color and Opacity Over Life parameters appear.
• Over Life: Particles are tinted based on their age. The Gradient Editor defines the
range of color that each particle assumes as it ages, beginning with the leftmost
color in the gradient, and progressing through the range of colors until finally
reaching the rightmost color at the end of its life. An additional control at the top
functions as an Opacity Over Life control.
Note: For more information on using the gradient controls, see “ Using the Gradient
Editor ” on page 485.
