I'm completely new to this. Is it possible to add bones to a photograph, like the one cat below and then animate its tail so it's moving? (Add a long bone to the tail and bend it) Or am I required to cut the cat into pieces and animate each piece? (Cut the tail into 10 images) http://uk.frontline.com/Style%20Library/images/contact_us_cat.png Is there a tutorial that shows how this is done? Regards, Daniel
