going through interactive clothes problem

Hi, I have some problem with interactive clothes from unity 3. I have a ball and a clothes, but for some reason the ball is going through the clothes instead of making collision. I’m very confused because I don’t know why it happened. Anyone have idea about that problem?
Thank you…

May be your ball is too small for the cloth to collide on, try scale your ball up to make the cloth able to collide.

And the following would help to adjust the cloth easier to collide and “stops” on an object

  1. Increase the damping
  2. Increase the friction
  3. Increase the collision response
  4. If you can adjust the “density” of the topology, try to increase it. But don’t make it too dense, it will slows everything down.
