You're gonna make me learn mission editing. I had a thought on turning way points. I read there's two ways of doing it, Turning Point and Fly Over Point. I wonder if you can break the turns up into smaller turns to make them smoother. Instead of say, one 60 degree turn at a way point, make them do two successive 30 degree turns.
I hadn't considered you were using a follow task, though that makes sense. I don't know squat about what's capable in mission creation/editing, but can you make the AI do sub tasks? Primary task- follow, sub task- initiate 1st 30 degree turn at turn point, initiate 2nd degree turn at second point?
I'm gonna have to learn how and experiment.
