Check Spline collisions (Pathfinding)

[_Aka_]

So If I understand correctly, you want the controller at the end of the spline to look at the last cp's orientation instead of the tangent of the spline at the end of the spline. Right?

If so, the only way I think about needs coding:
You can use the OnEndReach event of the controller to disable the controller once it reaches the end of the spline, and then orient your controller however you like.
You can also modify the code of the controller/override the controller's code, and add a special case when the controller reaches the end of a spline (RelativePosition == 1) in the code defining the orientation. A good entry point would be the method ComputeTargetPositionAndRotation
