I'm trying a fairly simple thing (so I thought); drop a sphere onto a piece of cloth, which is constraint at it's outer edges.. Butg the sphere doesn't seem to react to the cloth-object (I made the sphere a passive collider, and attached gravity to it...

example playblast:

It seems so simple, can anyone help me?

thanx
