When using the Physics Basketball Net & Ball prop (http://city.reallusion.com/ContentPreview.aspx?i=JICd9fce5ad4a4e071b5&g=GS634545170497417354). 

I notice every time I press play the net falls down, even when I brought in the infinite plane prop. I also have the soft cloth and rigid body simulation on.
And I also have the nets physic activated.

But when I press play the net just falls from the goal. Should I create a weight map for the net and just have the basketball rigid body simulation on?
