Hi, I was able to get this to work on a document I have open, per below following script/1
However, trying to get this to work in the context of another below script/2 that loops thru 3 different masking layers, but in this context getting this following error >>
"Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop. - The command “Select” is not currently available. Line: 40 -> executeAction( s2t( "select" ), descriptor, DialogModes.NO );"
Since the selectLayer function was working fine on my system in the context of script/1, I'm guessing the glitch has something to do with not correctly pointing to the dupDoc, or somehow not making it activeDocument properly. thanks in advance for any insights
script/1
