Has anyone seen this post where a guy got hold of Havok Behavior Tools, and then posted a download for it. I snagged one, but I will not post the link to the download, for safety. Post is http://forums.nexusmods.com/index.php?/topic/624251-progress-in-behavior-filesalmost-done/

He apparently made a new Behavior.hkx and loaded it into the game. Watching the video he provided, it seems true. Using Havok Behavior is really confusing, with states, transitions, clips, and nodes. I haven't been able to do any new .hkx's though, because it's very hard.
