Hi!
I need to rig a tail for a creature that needs a bit more control than a simple fk chain. Coming from Maya I'd like to define a custom spline-curve where the cv's are getting closer and closer towards the end of the tail. I'd then create a spline-ik that controls my bind-joint-chain. I'd then put a fk-control-chain on top by simply skinning the cv's to those extra fk-joints.
The default apex-rig-component only lets me create 4 controls (root, rootcv, tipcv and tip) and they are equally spaced. So my first question would be if there is a way using apex script (which I'm familiar of on a beginner-level) to "break" the standard-spline-ik so that I can pipe my own spline-curve in? (I know that H21 has some new spline-ik-component, but I have to stick with H20.5)
Thank you very much!

Hi, there.
Yes currently that is a limitation with the autorig components.
I have set up a simple component that will hopefully get you up and running
