Thanks Anthony. Just for info purposes. Also did a pretty cool transformation this way as well in which I had Posette change into a leopard woman. However instead of making one invisible, I simply used the size dials to hide the leopard woman figure inside the normal Posette in frame 1 and then did the opposite at frame 10 thus creating the effect as the animation ran the frames. As for quaternion. Not sure but isn't that what them aliens eat?
