Batch save for 4096+ variable images - SERIOUS GURU NEEDED

[achromatichouse]

Hello, I'm a graphic designer who has been given quite a weighty task. I have an image of a man who is broken into 4 separate parts; head, torso, legs, arms. Each of his separate parts are in a group layer containing 8 different color variations of said parts (ie. in ARMS group folder, there is a layer of red arms, blue arms, etc.).

I NEED to have flattened jpgs of every single possible color combination, which equals out to 4,096 variations. I wanted to know if there is some sort of way i can tell photoshop to run through each of those variations and save all 4,096 files as fully flattened jpgs. I've already done a similar project with only 2 variations, turning layers on and off and saving the things myself, trying to remember naming conventions, and it was a nightmare. Trying to avoid that nightmare again - PLEASE HELP

Thank you for your time

Hi, and welcome.
If you have Photoshop CS4 or CS5 this script should do what you want.
Copy and paste the script into ExtendScript Toolkit, this gets installed with Photoshop
This utility can be found in the relevant folder:-
PC: C:\Program Files\Adobe\Adobe Utilities
MAC: <hard drive>/Applications/Utilities/Adobe Utilities
The script needs to be saved into:-
PC: C:\Program Files\Adobe\Adobe Photoshop CS#\Presets\Scripts
NB: Vista and Windows 7 you will have to save it elsewhere and copy it to this folder due to permissions.
MAC: <hard drive>/Applications/Adobe Photoshop CS#/ Presets/Scripts
If Photoshop was open, close and restart Photoshop so that it can pickup the new script.

function main(){
if(activeDocument.layerSets.length != 4) {
    alert("You do not have four layersets!");
    return;
    }
outputFolder = Folder.selectDialog("Please select the output folder");
if(outputFolder == null) return;

To use:-
The PSD must be open in Photoshop
The PSD must only have four layersets (groups)
File - Scripts - select the script
It will prompt you for an output folder, once you have selected this everthing is done for you.
The files will be put in the output folder with a name of DocumentName-0001.jpg etc.
All the best, Serious Guru

your posts simply put me in Awe Paul MR....... Damn you bgood! with that stuff

[achromatichouse]

Paul MR, you are a life saver! This is sheer brilliance, I can't even believe this was actually possible!! THANK YOU THANK YOU THANK YOU THANK YOU!!!!!

You're the man!

Hi again Paul MR, just one more quick question for you:

If I wanted to add a 5th variable, would I just copy the various parts such as

for(var d in Parts3){
var p3 = Parts3[d];

and the various other lines like that and change it to Parts4 and "e"?

Thank you so much for all you've done, I really really wholeheartedly absolutely appreciate it!

[Paul MR]

yes, here is the full script..
