Change the Trap Shape parameter on the 

Outside tab to Box.

Switch back to the Layers tab and Shift click the Visibility icon on the Box Trap layer to 

toggle the other two layers off. This will help us to better see what we are doing with this

Since the Waves trap tendrils are white, let s make the Box trap shape a different color.

In the gradient editor, edit the set of white control points so that the Red, Green, and Blue 

settings are 145, 147, and 253, respectively.

Select Link Color and Opacity from the Gradient menu. This allows us to move and edit 

the color and opacity curves simultaneously. Also, make sure that the opacity part of the 

  gradient editor is visible   click the small opacity button to expand it if necessary.

G     

Insert a new point in the gradient editor. Set the Opacity of this control point to 0. Also 

set the Red, Green, and Blue settings to 0 to create Black.

Now Insert another control point to the right of that one. Change its Opacity to 255 and 

make it black, also. Click and drag this point until it is positioned just to the right of the 

transparent point.

Although the exact location of the transparent areas may differ slightly, your image and gradient 

editor will look similar to this:
