I tried several times to recreate the mesh from the vine tutorial and no matter way it doesn't come out right.
Can you show how you created the mesh from the vine tutorial?
I've added a screenshot of my attempt at copying what you did.
You can see on the right when I try to rotate the bone the mesh on the bitmap doesn't follow, like yours does on the left.
Thank you
