I'm hoping someone can help me out with this, I have some gems in my dungeon that are double size but the icons are still the original (blue, green, red). I just need icons that are exactly double, no new artwork or anything. But I don't know how to set up the gfxIndex files or the right dds settings or anything like that.

I bet for people who have done other icons this could be made in like 1.2 minutes, can someone help me out?

I can
Just three gem icons bigger in size ?

that's it, double width and double height of the picture, very simple, thanks!

I've sharpened them a little bit but they are still a little blurry. Let me know

It's good, works well, thanks!
