Random opacity for multiple layers in layer group (or selected layers)

Hello,

Is it possible to randomly set a random opacity value to multiple layers at once?

I maganed to do it for one, but I would like to set an unique random value for each layer in a group, or selected layers if that is easier...

Many thanks in advance!

Barry

I did some research into scripting on my own... I think it's not possible to do it if layers have duplicate names, but if you have layers with unique ad logic names, you can do it in an easy for loop:

if (app.documents.length > 0) mainScript();  
  
function mainScript() {  
     
for (i=1;i<=5;i++) {
     var myLayerName = "Layer " + i;  
     var myLayer = activeDocument.artLayers.getByName(myLayerName);
     myLayer.opacity = Math.floor (Math.random()*101);
     }
}

This gives a random opacity to Layer 1 through Layer 5.

It needs a bit more setup in the document itself, but that's okay for me.

    You can use layers IDs that are unique. This way you avoid problem with duplicates.

      I would think that you may be able to set multiply layer to have a  particular random opacity at once  not multiply different random opacities at once.
