FIGURE 46.27
The Ray effect extends a given number of rays out from the effect center.
Star
The Star Lens Effect radiates semitransparent bands of light at regular intervals from the center of the effect.
It uses the same controls as the Glow effect, with the addition of Width, Taper, Qty (Quantity), and Sharp
values. The Width sets the width of each band. The Taper value determines how quickly the width angles to a
point. The Qty value is the number of bands, and the Sharp value determines how blurry the bands are.
Figure 46.28 shows several Star effects with (from left to right) 3, 4, 5, 6, and 12 bands.

FIGURE 46.28
The Star effect lets you set the number of bands emitting from the center.

Streak
The Streak Lens Effect adds a horizontal band through the center of the selected object. It is similar to the
Star effect, except it has only two bands that extend in opposite directions.
Figure 46.29 shows several Streak effects angled at 45 degrees with Width values of (from left to right) 2, 4,
10, 15, and 20.

FIGURE 46.29
The Streak effect enables you to create horizontal bands.

Auto Secondary
When a camera is moved past a bright light, several small circles appear lined up in a row proceeding from
the center of the light. These secondary lens flares are caused by light refracting off the lens. You can simu-
late this effect by using the Auto Secondary Lens Effect.
