How do you make it so a square is seen the same from all directions, like the priest's staff end? (the circle thing) also, does it have to be a square or can it be a rectangle? Thanks (sorry if this is a skinning question)
That is called billboarding. It can be done on any shape/model. To do it (assuming you're using 3ds max), go to the Utilities panel, user property editor, and check 'Full billboarding' or something.
