I am doing a repaint and when testing out progress i get a pink glow on some of the fuselage and some of the tail ONLY WHEN ITS IN THE SUN. What is causing this and how do I stop it? I am saving in Photoshop(same settings every time for everything i've done) bmp 32bit. In dxtbmp: dds dxt3. scaling filter set to point and prossesing set to none. I started a repaint 3 weeks ago but the hard drive failed so am doing a different one but that one was fine.
Any help is appreciated

P.S. i have some pics if wanted

Worked it out. The default Pacifica repaint was on the other textures behind it so I replaced them with the blank ones and all is well
