Thanks again, Ariel! Yes, I assume, it works, if everything in the scene uses the same chan file. Unfortunately in my scene things are different. The falcon has its pivot at 0,0,0 of course (when it's not animated). But I can't offset the pivot of the cockpit cam in 3ds max, so that it's at the same place like the falcon's pivot. And then there's a new Han Solo in my actual scene, which is an object sequence of 600 (!) items with the pivot at 0,0,0 originally as well (but sitting in the cockpit in front of the cockpit cam). So there are three different camera paths, which lead to this wiggling.
Maybe I could offset Han Solo's pivot in 3ds max, so that he might use the same chan file like the falcon's, but altering the falcon's pivot, so that it matches the camera's pivot seems difficult. Apart from that the view from inside the cockpit might look too static in case that would work.
But great ideas! I'll do some more tests to maybe get some controlled random motion.
