to be able to edit all the layers at the same time?..
like for example erase the same thing from say multiple face texture layers at once instead of doing it one by one?

i use CS4 .. but i also have CS3 ..

thx in advance

Some tools have the "effect all layers" option. You can also use masks and adjustment layers to effect all layers below the edited later.

i'll have to check it out .... cause it would be so helpful and help my work so much more

Thanks for all the Infos....:)

 i've never tried to erase from multiple layers but i've SHIFT-SELECTed a bunch of  layers to change all the FontFace and Size and things like that...

I've never tried this in Photoshop, but I've done it another program. I made a mask for one layer, and painted black on it to erase what I wanted to erase in the layer, then copied the mask to the other layers, then merged the masks down to get rid of them.

Another possibility (which I also haven't tried) might be to record your erasure as an action, then play the action back against the other layers.

huh never thought to do an action! thankyou i'll give it a shot!!

User (alpha) channels might be of interest too. It's just another fancy form of saved selection, and you can even use that quick-mask toggle thingy to edit an active channel if you need finer control over opacity that what feathering or other selection adjustments give.

As long as a selection is active, it'll work on whatever layer is active. So you can zip through layers deleting a selection. Doesn't seem to apply to linked layers or sets though, so you'll still have to go through each layer. (Might be my version though, still on CS here. Yeah, my software is a relic - but so is my computer.)

You may be able to record actions for going through the layers and deleting, and that action record should be usable with any active selection if setup right.

Alternately, masks are applicable to layer sets. So maybe Cap'n Jack has got the right idea? Just get all the layers you want the mask to affect in the set folder, and edit the mask at the folder level.

Photoshop's funny like that, in that there's more than one way to skin a cat.

Group the layer you want to edit, and put a mask on the group folder then you can erase whatever part of the layers you want  to reveal whatever is under the group.

great thanks guys!!

or......just merge all layers....not sure if thats good or bad...give it a go.
