Importing splines using Datasmith?

Hi dear community, I am struggling with creating a mathematically perfect spline in UE5. So far there is only one way to import splines from Blender to UE5, no solution for 3ds Max. Can someone point me to a direction so that I can bring splines into UE5, with datasmith or any other 3rd party solutions?

Thank you so much!

There is script but unfortunately it is not working on Max 2023. Anyone has new solution?

Still looking for a solution?
