Combining 4 greyscale images into 1 RGBA

Recommended Posts

My first post :)

I have 4 separate png files, which are simple greyscales. What I want to do is create a single png, where each of the original files will correspond to an individual channel of the end png.

I haven't had any trouble creating the RGB channels from the first 3 source files, but I'm at a loss as to how to directly edit the alpha values. How can I make the alpha channel of my final png take its values from a separate greyscale image?

Thanks in advance,
