I’m not sure if this has been addressed before and if there is a solution but whenever I download jet_flame_diamonds.dds and open it with photoshop I would encounter this error. I currently use the Nvidia texture tools exporter photoshop plugin. A couple of months ago I never had this particular issue. I have tried opening the file in gimp and paint.net and it also gave me an error. I’m not sure if it has to do something with the new afterburners that were changed a few months ago. Since I can still open the old jet_flame_diamonds.dds that I have used on skins I have made several months ago.
