Russell Backpack Rig

Backpack from beloved UP Character "Russell" 

Backpack Straps are parented to the bag controller so be sure to set the constrain value to one when setting keys on the backpack and straps. usually maya sets the value to "0" after putting your first key.

I'm not much of a rigger so apologies for the quality. only the top of the straps are attacked to the backpack.
