Hi,

thanks for the idea. I tried to control a couple of layers and it worked! Fine!

I made a null object and put this expression into a slider control:

Math.floor(clamp(value,2,8));

An on every layer which is controlled by the slider I put this expression to the opacity:

if (thisComp.layer(“Controller”).effect(“Slider”)(“Schieberegler”) == thisLayer.index) 100 else 0;

But now I think about the following: what if I have not only eight layers, but more. Is there a way to find it out by expression(or set the maximum number automatically)?

Like this: Math.floor(clamp(value,2,MaxValue));

I read something about try/catch, does this work or is there another way to achieve this?

Yours, Matthias

Dear Joe,

could you please upload a CS6-version of this AE-project for me(your CC-Version doesn´t work for me)? I´m very interested in understanding this workflow because I´m new in expressions and I hope to understand it an wanna use this technique for some of my projects.
Hope you read this,

yours, Matthias
