Spline mesh with strange collision

I have built a spline mesh as a ramp on which a ball can roll down.

At all spline points where the meshes are put together, the collision does not seem to be formed with the mesh.

The ball rolls down the ramp, but bounces at each spline point.

I use complex collion as simple for the test.
Even if I use a UCX shape for collisions, the ball bounces at every spline point (no matter if curved or straight aligned).

The bounce

My mesh is a simple cube with sufficient subdivision.

In the viewport the spline looks like this.

And finally my constuction script.

i have tried the following without success:

  • used auto generated collision

  • used complex collision as simple

  • used separated collision shapes

  • and built a cube in blender with additional UCX_Shape

Nothing works, the ball bounces at every spline point (no matter if curved or straight aligned).

What am I doing wrong?

I have found the error after all.

Well, what was the error??? I’m having the same problem.
