I have a rigged and weighted letter A. I particularly need to understand why, despite a nice gradient in the weight painting, a part of the deformation is nice and flexible (marked in green on the screenshot). And part is stiff like it's 100% weighted, though it looks like a gradient in the weight painting (marked red in the screenshot).
What I would like is that when I pose the bone, the deformation follows the weight-painting gradients on both sides. So it's flexible and smooth.
I would like to understand how to control this, so I'm more in control of the deformations.
I'm attaching a stripped down version of the .blend file.
