Back to Bourbon, my quirky military rabbit character, I've started to build an animated rig for the character. This took some careful consideration of joint placement, as to how he would move. I couldn't just Rig him as I would a homanoid character since this would restrict the movement of the pelvis.
Step one was simply adding all of the bones into the right orient and position and making sure they were 'linked' or parented into each other accordingly. (See the schematic view to the right hand side of fig.1).
The second stop I started to look into the different kinds of IK chain solvers I could deploy for my rabbits rig. See here I've also introduced a knee and foot control to counter animate twists and bends in the IK.
