Right; from what I've heard, the Walk Designer only works well for bipedal (two legged; I think all of the standard human figures work all right, as does the Raptor, but that's about it, aside from custom figures) models; for horses and such you either need to find horse animation poses (I remember seeing some SOMEWHERE, but I don't work with the horse much, so I didn't pay much attention at the time!), or manually edit each frame.
