.
Angle—Specifies the angle for the rays. You
can enter both positive and negat ive values so,
when animated, the rays rotate in a clockwise or
counterclockwise direction. This parameter can
be animated.

that appear in the lens flare. Rays are randomly
spaced around the radius. This parameter can be
