I have the following IK rig:
It works, but I would like the three IK bones to scale (along bone-y) when the IK (dotted) length increases or decreases. These three IK bones are not straight in Edit-Mode, I pre-curved them; the screenshot matches EDIT mode as well. I have IK Stretch option turned on, but it doesn’t seem to do anything.
I am essentially trying to stretch-compress a curved shape along it’s curve using this rig; it’s fine if the volume is not maintained.
