Hi everyone! I'm developing another automation for my work. Everything was correct, but I forgot a variable. Is there any script that can apply the mask that is on the Layer to the group it is in? The layer names will always be the same, as well as their groups.
Thanks for the help!

Having consistent layer names is useful for automation.

 

Having both unique and consistent layer names are even more useful.

 

This should be simple enough to do with an action, however, having both the layer and set with the same name means that an action does not know when to select the set with the same name as the layer.

 

If the RGBA layer is always positioned as the second layer from the top of the set/group of the same name, then an action can select by relative position 2 layers up (as long as the layers that it traverses are visible).

 

Same for the other named layers, if they are always in the same position in their respective sets, then a relative position layer selection can be made.

Otherwise, a script would be required to select the parent set.

 

Do you know to script?

 

P.S. Do you also wish to remove the layer masks from the original layers after they have been applied to the set/group of the same name?

 

Is this a stand-alone automation, or will it be incorporated into something else?

Hi Stephen, Thanks for the reply. It will be a separate automation. The main layers (with the masks), will always be in the same position, but the amount of adjustment layer above them can vary, so I can't do it using actions. And yes, the mask has to be removed from the main layer after being applied to the group. Unfortunately I don't know how to create scripts, I just change some existing ones for my work needs.

How does it sound if I provide the code to work with the RGBA set, then you can copy it and modify for each of the others?

All you need to do is copy the seven steps between the block comments (with or without their associated line comments) into each of the 3 placeholder comments for the other layers. You then only need to change the absolute layer name parameter from "RGBA" to the new child layer name in each case, the rest of the steps are relative.

 

/* RGBA layer set */
// Select the child layer by name, not the parent group of same name
selectLayerName("RGBA");
// Select layer mask channel
selectLayerMaskChannel();
// Load selection from mask channel
selectionFromMask();
// Remove mask from child layer
removeMask();
// Select parent layer set
activeDocument.activeLayer = activeDocument.activeLayer.parent;
// Add mask to set
addMaskFromSelection();
/* RGBA layer set */

/* effectsResult.RGB CC */

"The main layers (with the masks), will always be in the same position, but the amount of adjustment layer above them can vary, so I can't do it using actions. "

 

Adjustments layer need different input? You can turn on modal control to manually set adjustment while playing action.

 

When it comes to part with mask when layer always have same relative position, select top most layer using shortcut then use shortcut to select layer below before deleting mask. If your layers always have exactly same name then target them by name. In case that layers stack have layers with the same name, action will always select layer which comes first so it is best to have unique layer names.

 

Difficult part is to record action which will work in different situations with different layer naming convention and different order. If you are running action starting from Background layer and controling everythuing then you should not have problem.

Agreed 100%! This could be easily automated with an action if the layer set was named differently, such as "RGBA-Group" with the layer being named "RGBA", then the action would be able to record the absolute selection of the layer vs. the group, without needing scripting to select the child layers parent group.

The code below would drag a Layer’s Layer Mask to its Group unless it already has a Layer Mask.

@c.pfaffenbichler - That's a useful bit of code, skipping over existing layer masks, thank you for sharing.

 

P.S. I just had time to set up a test and I really like how you loop over the layers/sets and compare the names, rather than hard coding in a fixed set of names!

Stephen's Code worked perfectly. Really if the groups had different names it would be much easier, but it's something I can't change.
Thanks Stephen and everyone for the help!
