I hate adobe and have been actively trying to switch away from them for a while. I work in game development, though, and for some reason no one has made it as easy to directly modify the alpha channel of a texture. It's something I have to do a lot and is probably the one thing keeping me from using krita or affinity photo.
@Nachorella
Gimp can do that if I recall correctly.
@kde
I'll try it again, looks like it's come some way since I last checked.
@Nachorella @minecraftchest1 I do that a lot in GIMP: right-click a layer, "add layer mask", and it makes a secondary grayscale layer that works like a second alpha channel, that you can directly draw on, apply filters to, etc. A lot of my stuff has solid-color layers with all the work done in those layer masks.
I might be misunderstanding but that sounds different to a specific alpha channel. Sometimes in game art you'll store extra information in the alpha channel of a texture. Or even pack four different grayscale images into the rgba channels of a single texture. Is it easy to do stuff like that?
@Nachorella You can right-click a layer and Apply Layer Mask to bake it into the main layer's alpha channel (or Merge Visible Layers to combine all layers and their masks).
I think you *can* work with individual R/G/B channels in GIMP, or at least add a Channels tab where they're visible separately and you can add arbitrary channels; but I don't have experience drawing on the channels independently like that. But my gut says it may be doable.
