Paint.NET alpha channels.

How to make an alpha channels on Paint.NET?
I know I could use photoshop or gimp, but I can’t install photoshop and there is no vtf plugin for gimp.
SO I am using I can’t figure out how to make alpha channel. Help please.

Don’t think you can.

Why don’t you just use VTFEdit instead?

Yeah, I mean, with VTFEdit it is as simple as just going to the file menu and pressing import.

And, besides, VTFEdit probably has more options for editing VTF after import than the Paint.NET VTF plugin, anyhow.

Actually I am absolute that there ARE vtf plug ins for gimp. Also why not use gimp then VTFEdit (said by others). You can’t use a GUI to create .vmts on anyway.
