Make alpha dependent on RGB
#4
Is this for one of those games engines that uses the alpha channel independent of the image?

I do not know, this might work

Take a duplicate of the image.
Colours -> Colour curves and adjust the green curve to suit.
Layers -> Mask -> Add layer mask with greyscale copy of layer option
Copy the original image and paste into the modified
As far as I can see that now has the original RGB and an alpha channel based on green.
some screenshots of that sequence. https://i.imgur.com/PNvwxOQ.jpg
You can apply the layer mask Layer -> Mask -> Apply or I assume exporting in whatever format ( tga ? ) will do.
