Just playing around with the latest Blender alpha and have some problems with the IK. What I want to create is a IK leg that is controled through Empties. Please take a look a the picture.
Here you can see how the leg looks like. I want the thigh and shin stay put with the plane that is described by the chain root, the knee empty and the foot empty. In other 3D apps this is called a pole vector chain, the knee empty being the pole vector. I have drawn in a blue plane so you can see what I mean. I want to be able to use knee as director of the thigh-shin-chain. How can I set up such a ik leg.
here is the Blender file, just in case
thanks in advance
