Thanks Michael, much appreciated.
I’ll try it as soon as I ump back into that project.

Can you share the way you’re doing it?

[David Cabestany]

Thanks Dan, it partially worked. The first rotation from -90 to 0 works ok, but then nothing happens. If multiply the 360 by -1 then it’s the second rotation the one working, this one goes in the opposite direction.

So I tweaked the expression to this:

yRot=thisComp.layer(“rot”).transform.yRotation;

if
(yRot<0)
{
r=thisComp.layer(“rot”).transform.yRotation%360;
}
else
{
r=thisComp.layer(“rot”).transform.yRotation%360*-1;
}
x=linear(r,-90,0,2700,1749);
y=linear(r,-90,0,1640,880);
[x,y];

And apparently it works, I haven’t tested it extendedly but by scrubbing the timeline seems to be doing the trick.

Thanks again.
David.

Is there a way to have the expression work in both directions?

[David Cabestany]

There’s a ascript for that, it’s called masksToLayers.

[David Cabestany]

What about a custom property, like a slider, for example?

[David Cabestany]

Thanks a lot Dan.

Is there a way to tweak this expression to make it work with a shape layer instead? I tried replacing mask with path and then the name of the path but all I got is the following error:

function “path” is undefined.

What would be the name of the function in a shape layer, then, specifically the path?

Best,
David.

[David Cabestany]

Yeah, I guess it has to be that. I’ll try changing the width and tracking values, if that doesn’t work I’ll have to animate it manually.

Thanks for your help.

When I added the loopOut(“cycle”) expression to the slider it doesn’t do anything. The keyframes work fine, but as soon as they should start looping they don’t.
