I've just grabbed the latest XNA4.0 version and implemented 2 simple cube bodies falling onto an immovable plane. This seems to work really well except that the cubes never quite seem to come to rest once they have bounced around - instead they continue to slide very slowly over the base plane indefinitely. Can someone offer me some advice on what I'm missing here? Do I, for example, need to add some lower velocity constraints or something similar? The cubes are all pretty much implemented using defaults - side lengths of 1 and BouncyRough material. The plane has NormalNormal material. Any help gratefully received.
PS Great library and many thanks for the XNA4.0 update!
