I'm working on an animation and I'm trying to build an armature to unfold a chinese food box like this one; to a flat paper page:
Once flat, it should look like this :
But I've got hard times to make the armature work. It's no problem to have the main faces working; but I don't know how to handle the paper "folds" in the corners... I've already tested by assigning manually several times and in different ways the vertexes weights; but I don't get any convincing results.
How would you do / can someone help ? Here's my actual file.
