I'm having a problem when painting in Blender where lines are appearing in areas of the fuselage that I'm not directly painting on. I've included a couple of screenshots - the first one shows where I've painted small areas around some of the windows and the lines appear on other areas, and the second screenshot shows the UV Map which looks like something has changed compared to other UV Maps I've seen for the A320. Latest version of Blender but I also tried previous versions and the same issue happens. Any help much appreciated.
