Hi all,
Don't know if you take requests here, but I figure it couldn't hurt to ask before I go and do this ~150 times

I'm doing work on the Alpha Channels for some game models, and the procedure I follow to get the best in-game result is as follows:

1) Select All
2) Colors->Desaturate (Luminosity)
3) Copy, Undo
4) Add Layer Mask -> Transfer Layer's Alpha Channel
5) Paste, Anchor, Apply Layer Mask
6) Overwrite current file.

Not a difficult process, but tedious as anything.

If someone could write me up a script or plug-in to do this, I'd be forever grateful.
I admit to knowing next to nothing about scripting in GIMP, so if what I'm asking for is too complex (or impossible), feel free to tell me to go away!

Regards,
Doug

maybe if you detail better the steps (for instance: 3=copy what? create a new image or a new layer?...etc), later I may give a try

edit: maybe you may add an example (xcf)

Taking your instructions at face value, I think you're going the long way round.

If you do this, do you get the same result?:

1) Add layermask - "Grayscale copy of layer"
2) Overwrite current file

Mate, you're a genius, that works great!

Any idea of how I can do that in batch for all my images?
I've had a look at the BIMP plug-in, but I can't see a way of using it to do this.
From what I can gather, I now need a script to do what you described, and use BIMP to batch process my files with that script?
