So I have this pencil case:
And I would like to open it like this:
Note : I'm not trying to open the zipper, just to deform the pencil case in a realistic way. I figured the best way to do this would be by rigging it, but the thing is, I don't know much about rigging. I tried this :
But, as you might have noticed, I kind of have no idea what I'm doing and it really does not work.
So, would you have an idea of how to get a realistic opened pencil case, with or without rigging ? That would really help me !
