Ok, I have an Image in 8 bits per channel mode on Photoshop. When I try to save it doesn't let me select the A8 R8 G8 B8 option.
Why I can't do it? There's a special mode that I have to choose to make this option available?
Here's a screenshot. Only the XRGB (leading zero) it's availabe and I need the leading Alpha option.
Sorry for any misspelling
You can't select ARGB because there's no alpha channel in your document. ARGB requires an actual, for real alpha channel.
I'm not sure why your application requires it, but a simple way to make that selection available is to add an empty alpha channel, or select a layer and save the selection (which creates an alpha channel).
I tried to make the texture with the software that makes the textures and now it works. I still not know how can I make the headers available in photoshop by the way but I'll mark this as answered.
PS: I'll mark this answer as the solution in 2 days if no one can give me a solution. Thanks for everything.
