I'm doing a rig and I want to modify the shape of my bones: in particular the control bones of torso.
Here a simplified situation: I want to change the shape of my octahedral bone in the circle behind.
The problem is this: in pose mode my bone, after choosing the custom shape, disappears.
Furthermore if I switch to object mode the bone will come back with the circle shape.
Here the point is: I need tools to move my mesh easily and a circle around the waist is perfect but in pose mode doesn't appear . . . i can't understand why since the method used should be right.
