Script for deleting Hidden Layers which are not used in any Layer Comp?

Hello.

I've turend the web upside down searching for a script that would do the following:

  1. Search through all the layer comps in the document
  2. Check which layers are hidden on all Layer Comps
  3. Remove/mark with color the layers found.

If anybody can provide a script that would do such a thing - it would be highly appreciated.

Regards,

Fade.

    This should mark those layers Red...

    Hi, I'm a little late to this post, but the script here works great.

    However, I'm wondering if it's possible to have a script that would instead go through all layers & smart objects and delete hidden layers.

    That would be amazing if possible?

    Thanks

    Chris

    Chris, scripts previously posted in this topic do just that, go back to the top of the thread and work your way down (post #5 and or #8).

    Thanks for your reply Stephen, however I have tried both of these scripts, and both delete all layers within a PSD, regardless of whether there are smart objects with layers visible or not, and it also deletes visible layers that are not part of any smart objects.

    What I was hoping for, was a script that would only delete hidden layers, both standard layers in a PSD and those that sit within smart objects.

    Edit: Just to be clear I am not using layer comps

    Cheers

    Thanks for this great script.

    A thought on an improvement: it seems that if you have a layer group set to visible with all of its layers turned off, the delete script leaves these layers intact. Is there any way to script this at the layer level as well, or could this be a bug?

    The norm is ".jsx" the script will require Photoshop CS3 or better.

    It's best to use ExtendScript Toolkit (this gets installed with Photoshop) to copy the code and save it out.
