•
Pick From Color Range: Particles are tinted at random, with the range of possible colors
defined by the Color Range gradient editor. A point on the gradient is randomly chosen, so
the relative sizes of each color region determine the frequency of the color being used.
For more information on using the gradient controls, see Gradient editor tasks on page 137.
•
Take Image Color: When you choose this menu item, each new particle’s color is based on
the color of the image at the position where the particle was generated. This menu item is
available only when the Shape pop-up menu in the Emitter Inspector is set to Image.
•
Color Over Life: The Color Over Life gradient editor, available when the Color Mode is set to
Over Life, 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. For more information on using the gradient
controls, see
Gradient editor tasks on page 137.
•
Color Repetitions: Available when Color Mode is set to Over Life, this slider determines the
number of times the gradient color pattern is repeated over the life of the particle.
•
Color Range: This gradient editor appears when Color Mode is set to Pick From Color Range.
Use it to define a range of colors used to randomly tint new particles. The direction of the
gradient colors is not relevant, only the number of colors that appear in the gradient. The
Color Range parameter has the same controls as the Color Over Life gradient editor.
•
Scale: A slider that defines the scale of every particle of a cell. Click the disclosure triangle next
to the Scale parameter to reveal separate X and Y scaling subparameters, which can be used
to resize the width and height of generated particles. This control affects the initial scale of the
particle (compared to the Scale Over Life behavior in the Particles behavior category).
Scale set to 200% Scale set to 50%
Note: When you use an image as a particle cell source and set a low Scale value, set the render
quality in the Render pop-up menu (above the Canvas) or the View menu to Best (choose
View > Quality > Best).
•
Scale Randomness: A slider that defines an amount of variance in the scale of generated
particles. A value of 0 results in no variance—all particles from the selected cell emerge with
the same size. A value greater than 0 introduces a variance defined by the Scale parameter,
plus or minus a random value falling within the Scale Randomness setting.
