Flare Inferno Parameters 361
Inter face
You add the Inferno effect to other lens flare
effects. Inferno is selected in the Preferences panel.
The lens flare effect you are adding Infer no to,

work correctly. The Inferno panel is divided into
two sections: Settings and Parameters.
Settings group
Gaseous—Alooseandsoftpattern,oftenusedfor
clouds and smoke.
Fie ry—Fractal patterns w ith bright, well-defined
areas, of ten used for fires.
Electr ic—Long, well-defined tendril pattern that
can be used to produce arcing electr icity, when
animated. By adjusting the quality of the pattern
to 0, you can create the effect of water reflection.
Lock E f f ect—Locks the inferno effect to the lens
flare. When the lens flare m oves across the screen,
the inferno effect moves with it. Use this option
when you want the noise pattern to move with the
flareforeffectsliketorches.
Lock Noi se —Locks the inferno noise patterns into
the screen. When the lens flare is animated and
moving across the screen, the noise pattern stays
in one spot and the flare moves through it. This
is of ten used for creating plasma t rai ls and cloud
patterns.
Motion—When you animate the inferno, motion
specifie s how fast the inferno patterns move in
the direction set by the Direction spinner. For
example, if you want to simulate a raging fire, you
want the frac tal p atterns to move upward. This
parameter can be animated (page 3–349).
Direction—Specifies the direction, in degrees, of
the inferno effect motion. By default, 0 is aligned
in the 12 o’clock position, and works clockwise.
This parameter can be animated.
Note: The Motion and Direction spinners control
the motion of the fractal pattern in the X and Y
directions. You can control the Z direction using
the Speed option under Inferno Parameters.
Quality—Specifies t he overall quality of the fractal
noise patterns in the inferno effect. Higher values
result in more iterations of the fractals, more detail
in the effect, and slightly longer render times. T his
parameter can be animated.
Reseed—The number that the fr ac tal routines use
as a starting point. Set this spinner to any number
to create different fractal effects. The Reseed
button randomly selects a new number.
Parameters group
Size—Specifies the overall size of the fractal
patterns. Smaller numbers produce small, grainy
fract als. Higher numbers produce larger patterns.
This option can be animated.
Speed—Sets the overal l speed of the turbulence in
the fractal patterns as they are animated. Hig her
numbers produce faster turbulence in the pattern.
This parameter can be animated.
Base—Specifies the brightness of the colors in the
inferno effect. Higher values result in brighter
color ranges and brighter infernos. Lower values
result in dark, softer effects. The Base spinner
only affects Fiery and Electric inferno types This
parameter can be animated.
Amplitude—With the B ase spinner, controls the
maximum brightness for each portion of the
