Specifies the shape in the source layer that you want to use as the emitted wave. Contour numbers the
Contour
shapes by their order in the frame from top to bottom, left to right. The shape in the top left corner is number 1.

Wave Motion controls for the Radio Waves effect

Wave Motion controls specify how the wave emits from the center point.
Specifies the number of waves per second flowing out of the producer point.
Frequency
Specifies the speed at which the wave travels from the producer point once it is born. This does not affect
Expansion
the number of waves per second.
Specifies the rotation of the shape at birth around its center point. To animate the rotation, use the Spin
Orientation
control.
Specifies the wave's initial direction when Velocity is greater than 0. By default, particles are emitted from
Direction
the producer point in an expanding radial pattern.
Specifies the speed at which the wave moves in the specified direction.
Velocity
Controls the continued rotation of a shape after it is born.
Spin
Specifies the time, in seconds (including the fade-in and fade-out times), that the wave exists.
Lifespan (sec)
To prevent waves from abruptly disappearing when their lifetime ends, use the Fade Out Time control.
Specifies whether the waves bounce off the edges of the layer and back into the scene. This is effective for
Reflection
generating displacement maps for use as water ripples.

Stroke controls for the Radio Wave effect

Stroke controls specify the appearance of the wave's stroke.
Controls the appearance of the stroke that defines the shape. The outline of the shape is animated in the wave
Profile
that emanates from the effect point. The quality of the stroke is defined as a 3D wave type.
Specifies the color of the stroke.
Color
Specifies the maximum possible opacity of the stroke. The actual opacity of the stroke takes into account
Opacity
this setting in conjunction with the Fade-in Time and Fade-out Time controls.
Specifies the amount of time it takes the wave to fade into view. Fade-in Time is measured in seconds
Fade-in Time
and begins with 0 opacity at birth. For example, if the Lifespan is 3 seconds and Fade-in Time is 1 second, the stroke
is completely transparent at birth and fades smoothly to full opacity at 1 second.
Specifies the amount of time it takes the wave to fade out of view. Fade-out Time is measured
Fade-out Time
backward in time from the end of the Lifespan. If the Lifespan is 3 seconds and Fade-out Time is 1 second, the wave
begins to fade out at 2 seconds. If the sum of Fade-in Time and Fade-out Time is greater than the Lifespan value, the
intersection point of the two fades is calculated so that the wave does not reach full transparency. If either Fade-in
Time or Fade-out Time is longer than the Lifespan, that amount is truncated to equal the Lifespan.
Specifies the width of the shape at its birth. End Width specifies the width of the shape at the end of its
Start Width
lifespan.
