Hello
I am making a basket ball game and I am facing a problem with the basketball net (rack) mesh collider as the ball do not go through the net .
Is there anyway to edit the mesh collider or I have to do something else?
Look at Cloth.
You are here again buddy 
There is a problem which is the board should be be treated as mesh collider and the net should be treated as cloth, so how can I add this?
