Strange physical behavior

Hi,

my scene consists of a simple blender model with a mesh collider
and a rigidbody sphere with a constant force so it rolls on the model.
I have to use continous collision detection because the play will be able to shoot the ball fast.

But it only jumps around on it. Have a look and you know what I mean.
I don’t know how to repair this.

Can anyone help?

Make sphere size as an 1.
Physics don’t like if rigidbody have the size not a 1.

thanks for the answer.

It works, if I set the size to 0.1 .
I don’t know why but it works.

Maybe someone else knows it…?
