Brilliant, thank you so much! Funny enough, I just had decided that I will try porting one of Unity’s C# tweening libs (iTween or Hotween) over to UE4 for my game when I stumbled across this thread… perfect timing 
One question: Do you know of a way to make use of the landscape splines for the MoveToSpline task? That way you could have actors follow a road without manually placing waypoints or an additional spline. I couldn’t find a way to get a reference to a landscape spline into the Blueprint, but maybe there is one?
