The way I've 'rigged' it so far, is actually not to rig it using joints or skinning, but to create a selection of deformers and have them controllable by a separate control. I'm now adding some blend shapes alongside this for some more complicated shapes. Below is how I've put it together, I can't see any problems at the moment, but is this the best way of controlling it? Or will I run into problems when animating. It seems to be able to do most of the movements it needs to in the animation.
It has two bends, a twist and a squash deformer.
The movements I have at the moment are these:
Hey Sam - it's alive! But won't you need it also to 'puff out' - as if it's inflating - for when it's panting, or squatting on its haunches preparing to spring?
Hi Sam
Your case is basically the Disney flour sack (Look it up). As long as you can move it in this way then your rig is fine. Treat the upper half of the case as the 'chest' and the lower as the 'pelvis'. The top corners as 'hands' and the bottom corners as 'feet'.
