Add splash effect to disappearing line in Apple Motion

In Apple Motion I have created an animation where a vertical line disappears in the centre of the screen and I want to add a small but effective circular splash effect, as the line reaches the zero visibility stage. Any help would be greatly appreciated.

The idea is similar to what I did, except the circles are not filled, and there are two instead of one.


It seems that two circles grow from the center and then fade out, one slightly later than the other.


This can be done this way:

- create a circle

- turn off fill and turn on outline

- keyframe the radius (in the Inspector, under Shape->Geometry) so that it starts at 0, then add another keyframe at the place you want it to reach maximum value

  • keyframe the opacity: add a keyframe for opacity, near the one where the radius is max, and set it to 100%; then move to where you want it to disappear, and set it to 0


Duplicate the circle, and drag the second one slightly to the right in the timeline. Done.
