Hey Roy, I've done a sort of 'manual' setup like this by writing a 'pointAtArclen' node and then wiring the rest with existing nodes. In my case I used aim constraints for each joint, but you can do something similar within your solver- get the orientation by figuring out where each joint needs to be on the curve and what the vector would be if you were aiming each joint at the next.
