Hi, I have a big problem with FSX. Recently, I installed some new aircrafts. They worked ok and everything looked ok, but then, randomly while I was playing with a plane's flaps, the whole plane became invisible. If I use the 1st person view in the Cockpit it's fine, but when I look at it from outside (from any angle) it's literally invisible, there is no plane (but the shadow and the lights are visible). This thing happens with every single aircraft (even with the default ones). Can anyone please help me solve this problem? I would really appreciate it! Have a good day.
