Yesterday I modelled the suitcase and today I plan on getting the rig and movements sorted so I can finally start to animate. I've read up on ways to make it move, and have created a set-up which I think so far is working.
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:
