Origins as both nruddock and Mr. Bently stated is very important. To give you an example where vendors screw up the orgins of props a lot is dangling prop earrings. They leave the origin at the center of the earring. So  if the character leans their head and you want to change the earring to match or look like gravity has taken effect, you have to move the orgin from the center to where it should be which is where it attaches to the ear. Because if you don't and you rotate the earring, it moves off the ear, because it is rotating around the center point which is below the ear. Move the origin to the attachment point and you can rotate to you hearts content to match how gravity would effect a dangling earring.

 

If you stop and think about it for a second, a door rotates at the edge not the center of the door, unless you made a revoling door. A lever door handle rotates at the center of the shaft not at the center of the lever of the handle. Pretty basic stuff.

 

As Les says play around. But don't do like me and screw things up a couple of times, before the light goes on and you have that, Oh now I get it momment, especially as it relates to prop scaling! :laugh:
