• 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.
• 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
within the gradient. The Color Range parameter has the same controls as the Color
Over Life gradient editor.
For more information on using the gradient controls, see
• Take Image Color: When you choose this mode, each new particle’s color is based on
the color of the image at the position where the particle was generated. This mode is
available only when the Shape pop-up menu in the Emitter tab is set to Image.
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%
