I would like to use Sith War Droids HD - 4X Upscaled Texture from NexusMods but I hear the author's mods all have issues with alphas. If anyone can suggest how I can correct this myself using GIMP (as I don't have PS), I'd like that.
From my experience, it's a bit of a struggle to notice the difference in the upscaling. Regardless, if you just go to the layer drop down menu and select remove alpha channel...that should do the trick in GIMP.
A couple of people have posted some methods to fix the alpha problem in the author's aio pack page. I have yet to try myself, but I intend to at some point. I hope to learn that program the author uses so I can do some upscaling myself.
