A white color on the gradient means the puffs will stay the same size or luminosity.
A black color means zero radius or no luminosity, while gray values are intermediate
values. High variation in the gradient will create random volume sizes.

Luminosity



For details on using gradients, look up ‘Using gradients’ in the index.

You can easily adjust the

luminosity of the particles

over their lifetime. This

is a powerful effect that

allows you to create rocket

exhausts or any type of

glowing fire.

The Luminosity gradient controls the amount of additive pixel blending over the

particle’s lifetime. A white color gives the luminosity value you defined on the Globals
page; a black color returns no luminosity effect at all; and grays give intermediate
values.

The left and right edges of the gradient correspond to the time of the particle’s birth

and death respectively.

Color Mix, Color



For details on using gradients, look up ‘Using gradients’ in the index.

This gradient controls the color mixing, over the particle’s lifetime, between the puff

color set on the Globals page and the color calculated by the Age Color gradient.

So it is the combination of the Globals Color, Age Color and Age Color Mix gradients
that gives the result. Each gray value represents a mixing amount between the base
color (set on the Globals page) and the color generated by the Age Color gradient.
A pure black means that 100% of the base color set on the Globals page is used to
draw the puffs; none of the Age Color is mixed into the particle color. A pure white
will color the puff with 100% of the Age Color gradient; the base color set on the
Globals page isn’t mixed into the Age Color at all. All intermediate gray values will
create a mixing of both color values.

For the Color gradient, the left edge of the gradient controls the color at the puff’s
birth, while the right edge controls the color of the puff when it dies.
