Koby.

It depends on what you want to animate...
If you want to animate the radius of the helix, link the "sRad" parameter to a slider.
If you want to animate the radius of the helix, link the "sOff" parameter to a slider.
etc.

That's more complicated to work on selected layers, because I split layers when needed and create new layers, thus changing the layer's selection. However, I've changed the script so it will not work on locked layers. So you could lock the layers you don't want the script to work on, and then launch...

Try this expression:
Where riseTime is the transition time. Koby.

The first argument to the ease function (where you wrote "value") must be a scalar, comparable to the 2nd and 3rd parameters. I don't know what you are trying to do, or on what property you've used this expression, but writing "time" instead of "value" might do what you...

Thank you Salvador for the correction, I've corrected the script of my last post, so it is without the error now. AE does not render 3d layers that are outside of the camera's field of view (for example, behind the camera). However, it WILL render 3d layers that are in the field of view, but being o...

My mistake.
That's some leftover I forgot to delete...
Delete that line, and everything should work fine.

I've changed the script that it will split layers if the opacity drops to zero and then raises back again, thus saving AE from rendering in that area. If needed, the script will split the layer multiple times, and will isolate every area of non-zero opacity in a duplicated layer. Salvador, I think t...

I'll try to do that when I return home in the evening.

Thanks Paul ! Salvador, First, if you change the line you've changed before: if (curLayer.opacity.valueAtTime(t,false)>0) to these 2 lines: if (curLayer.effect("Tint") != null) if (curLayer.effect("Tint")("Map White To").valueAtTime(t,false)[0]>0) You will no longer get...

I'm glad you like my script, and use it ! :) I hope it saves you a lot of render time, like it saves me. salvazalvi, This can't be an expression, because expressions can't trim layers... And even if you write an expression that makes the layer invisible (fully transparent) but not trimmed in the tim...

Instead of "time" in Mylenium's expression, add a Slider Control to a NULL object (or any other existing layer), pickwhip it's value to a variable t and multiply it by "Math.PI/180". Then use the Slider Control as the rotation angle in degrees: 0 - is the starting angle 360 - is ...

Check out Dan Ebberts's "Elastic Connection" expression:

I think that's the effects you were looking for (or it can easily be changed to what you want)

Koby.

Try this expression for the scale property. It will expand and shrink groups of 3 pictures each time together, every second. T1=0.2; T2=0.2; i = Math.floor((index-1)/3); if (time<i+0.5) s = ease(time, i, i+T1, 0, 100); if (time>=i+0.5) s = ease(time, i+1-T2, i+1, 100, 0); [s,s] Where: T1 is the time...

What you should do, just like Dan wrote, is something like that: (I assumed that before you reach the first comment, you wanted the position to be the original position of the layer) snapSpeed = .2 location = [[644,858],[2685,210],[2098,834]]; m = thisComp.marker; //FIND THE CURRENT MARKER if (m.num...
