I am trying a create Crowd AI simulation where AI can move on escalator using spline. Logic I have setup is one they reached Spline start Point, itween for Spline movement takes over but the problem I am having is first AI charactor goes through spline escalator smoothly and then one that follows jitters a lot before reaching the spline start point and goes through spline.
Here is the attached video of the problem I am facing
I am also attaching behavior tree logic
Is there some setting that I am missing here,
