Hello, I am trying to build the rig found in “Introducing Character Animation with Blender” but am running into some problems. The rig is based off of the Ludwig rig by Jason Pierce, in case you don’t have the book. I am trying to rig the foot so that rotating the heel.L/.R bones will rotate the bones on the bottom of the foot (ball.L/.R, Toe.L/.R, and toeDeform.L/.R, plus any other bones that should be moved in the walk cycle) in a straight line, as shown in the book. When I rotate the heel bone, only the toe bones rotates and the ball bone stays in its place. I can achieve this effect by physically moving the ball bone, but according to the book, I should only have to rotate the heel bone. Does anyone know how my rig is bad? Or should I just manually move the ball bone? I am a noob when it comes to character rigging, but I would like to learn how it all works. My model can be found at http://www.danielbakerdesigns.com/character.blend.
Thanks for your help,
