Sharp—Specifies the overall sharpness of the
streak.Highernumbersproducecrisp,clean,and

This parameter can be animated.
Taper—Controls the taper of the i ndividual spokes

Default = 0. This parameter can be animated.
Gradients—The gradients (page 3–392) are the

Infernos let you use lens flare to create explosions,
fire, and smoke effects and add a bit of fractal noise
to any part of the lens flare. This noise comes in
three types: Gaseous, Electric, and Fiery.
Interfa ce
You add the Inferno effect to other lens flare
effects. In ferno is selected in the Preferences panel.
The lens flare effect you are adding Inferno to,

Fie ry—Fractal patterns w ith bright, well-defined
areas, often 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 Noi se —Locks the inferno noise patterns into
the screen. When the lens f lare is animated and
moving across the screen, the noise pattern st ays
in one spot and the flare moves through it. This
is often used for creating plasma trails and cloud
patterns.
Motion—When you animate the inferno, motion
specifies how fast the inferno patterns move in
