Moving Platform

Hi,
Here are multiple ideas that can help you.

• Can you try to modify your setup so that it is similar to how the sphere is configured in scene 10_RBSplineController? Does this fix the issue?
  
• If not, try setting up something like in scene 11_Rigidbody, which does not use a spline controller, but a new script that applies a force (in your case it should modify the velocity) in the direction of the spline's tangent.
  
• Instead of computing the velocity by comparing positions, have you tried to set the spline controller's Speed property, and use that value, in combination with the spline tangent, to compute the velocity direction.
  
• The issue is probably not that, but is the gravity still applied on your rigidbody?
  

Let me know if none of this worked.
Have a nice day
