Try this:

—————————————–
n = 0;
t = 0;
if (marker.numKeys > 0){
n = marker.nearestKey(time).index;
if (marker.key(n).time > time) n–;
}
if (n > 0) t = time – marker.key(n).time;

ampX = 15;
ampY = 60;
freq = 5;
decay = 3.0;

angle = freq * 2 * Math.PI * t;
scaleFactX = (100 + ampX * Math.sin(angle) / Math.exp(decay * t)) / 100;
scaleFactY = (100 + ampY * Math.sin(angle) / Math.exp(decay * t)) / 100;

x=value[0] * scaleFactX;
y=value[1] / scaleFactY;

[x,y]
—————————-

You can change values of ampX, and ampY to get the desired results. You can attach them to sliders if you want.

Try to use: “Remove color matting”
Sometimes it solves everything.

Thank you for that, but this is not the case I try to solve.
I know how to control the position of the pin via nulls, via expressions etc after the pin is created.
The point is that once the pin is created by placing it with the mouse click – its initial position is set. If I change its position – the mesh is being deformed.
What I am trying to achieve is creating the new pin at the exact position without trying to aim with the mouse cursor.
Or when I place the new pin – I’d like to change its position WITHOUT distorting the mesh. Kind of “pen behind” stuff.
I’m afraid this is impossible without some script.
I’m not good at scripting, but if there is a possibility to add new pin via script – the problem would be solved I think.

This works only in two dimensions. There is no way in AE to establish 3d path.
If you take a 2d layer’s position copy all it’s keyframes and paste it to the mask’s path or shape layer’s shape – you got the path, but if you do it with a 3d layer – it will take only x and y, and simply ignore the z value.

Well, I was afraid you’d say so…
Thanks anyway.
