What I'm really trying to do is generate a path for an airship (balloon on top wooden ship suspended bellow), I want it to follow the path while looking as though it's just naturally flying towards its intended destination. I have the path, and now I also have the heading, one last final touch would be to have it rotate lightly on the z (forward) axis, as it rotates on the y (up) axis, to simulate the force of the wooden boat below. Currently its movements look kind of static. While I managed to solve the other movement issue (rotate towards heading), this one I'm at more of a loss for.. I've tried with rigid bodies and hingejoint, but paths apparently don't affect physics.
