I've been trying to reskin some common weapons lately and the problem that I can't open up the .DTX files with anything than DTXView. I tried using Black Angel Software's plugin for photoshop but I can't get it to work. But is there a plugin for Paint.Net or another way around it?
the only way to change the weapon skin was by rez but now rez is patched
It's extremely hard to get to see your reskin in-game other than through a hack.
