There's another havok-type setting, but I can't remember what it is. My memory is that it is not 100% reliable anyway.
(Amethyst, a poster on here, may know from all his work on bookcases and mannequinns??)
And, if the object is not a static ... so the player can pick it up ... then you'll have a hell of a time getting this to work, anyway. I have a note "pinned" to a door (with a knife, it appears, though not really), but 99% of the time the note wafts it's way to the floor when the player enters the room.
