I have created a sphere on top of a cube as follows:
And have set the sphere to be a child of the cube:
Then I added an armature to bend the square like this:
The thing is, since I set the sphere to be a child of the square, I have expected that from now, when I bend the square using the armature, the square would follow it. But it doesn't:
How can I set the sphere so it would follow the direction of any bending I do to the square?
