Simple Curve Rig with KineFX?

Hello,

i wanted to build a simple rig for a curve but struggled with the correct setup in KineFX. Basically I just want to have a curve with ~10 vertices that could be bent naturally with a controller on the last point. So ptnum 0 should stay in place (can rotate to compensate the rig) and the last point drives the IK chain. I can somewhat get it to work with a three point curve (that I resample later) but I don't get how to set this up with a finer sampled curve to get a smooth rig. Here are some pictures of what I have, what I want to get and a simple hip.




There is a good video by Brundlethwaite (https://www.youtube.com/watch?v=QbX0IF6c1qo), but it is 5 years old and I wonder if this task can be achieved in a much simpler way.

I'd be grateful for any tips.

APEX is used nowadays. Try this:
