Allright. For me its working and i think that scene at 2:39 on the video is made like this:
- Press the "lft ctrl+f11" so you get the free camera mode and then move the camera at a good distance from the aircraft.
-Then zoom with the camera "right ctrl+"*" key on the numpad (above the 9) so you can see the aircraft and then click the "," key on the numpad.
- Now the camera should be locked and tracking the plane.
And when it fires the mav, press again the "," key and it should now track the missile
I hope it works and it should, if u havent changed the keys in the options :)
