Rigging character's arm IK Spline and Geometry issue

So I'm using Maya's youtube video series of setting up a character rig and it's all going swell except this issue of creating an IK spline for the arm. I set up an RPSolver IK Spline from the Upper arm to hand IK Joints to create a decent spline, geometry following and whatnot, parented under the Arm_CTRL.

Now the real issue is when I'm told to create an SCSolver IK Spline from the Hand to Hand_End Joint. After parenting it under the Arm_CTRL as well, all the movements are perfect with the hand's geometry lining up with the Arm_CTRL but the geometry from the wrist to hand is disconnected and not following natural movement.

I've switched through different kind of splines between the different joints and whatnot, but the geometry either doesn't follow or the spline just ends up being messed up. Is there a simple mistake I'm doing or overseeing?

First spline looking good !


Second spline, with the same movement disconnecting the geometry and it not following



Basic movement like raising arm and wrist creates and arm cannon and ugly looking poses

You're missing a reverse node to 'turn off' the FK / IK on the other joint. It's a very common mistake.

Shameless plug, but I did cover this in one of my tutorial series.
