IK and Motion clips [SOLVED]

So I've got a really simple IK setup 3 joints in a chain, the goal is animated in a looping motion.
The only other animation is that the last joint in the chain rotates in the banking channel.

Everything works great until I make whole thing a motion clip and set it to loop, after that the IK kills the last joints rotating animation after the first loop.

IŽve attached an example, notice how the joint named "animated rotation" stops spinning after the first 60 frames. But if you turn off the IK it keeps spinning as it should:


Got this from tech support:

creating your MotionClip, you will have to assure to switch on the option "Bake Expressions",
so the IK will included correctly into your MotionClip. After creating the clip, switch off the IK-Tag
to have the correct animation.

Or a simpler solution is to just add an extra joint to serve as the tip effector for the IK.

It doesn't matter what people say about you, just as long as they're talking about you.
