Hey, I've been tearing my hair out trying to get Dota 2 shader masks to work.
I'm using GIMP, and ideally I'd like the ability to plug the greyscale images I make right into a channel (such as R or A).
This is so I can make the shader masks for Dota 2 work.
What's the best way of assigning a greyscale map (such as my specular intensity map) into a RGBA channel so Dota 2 recognizes it?
