I'm making myself a personal retexture mod for Fallout, all i wanna do is resize a normal texture because of it's exaggeratingly large size, however its hard for me to exactly accomplish that; Attempting to do so via Paint.NET makes the normal texture in-game look bad, this is because, at least for me only, Paint.NET doesn't have an option to toggle and/or export masks from DDS files (if i'm saying that correctly). So i tried other options, i tried DDS Viewer to resize, but for no reason whatsoever it doesn't work, as the size keeps resetting itself when i try to apply it. I tried using the Skyrim Optimizer Texture program, but no matter what i do, it does not detect the .DDS file.
So i am completely stuck, i have no idea what software i could use to resize the .DDS file to a smaller size, is there some sort of software out there than can guaranteeingly do so? Or is there some sort of way i can toggle Masks in Paint.NET? (Like an option i overlooked or a separate plugin).
