In this video, we will be creating a spine, and during the video, we will be exploring two different methods for creating an IK setup on a bone chain driven by a NURBS curve.

Download the scene file created in this video below. You can create your own rig from scratch by following along this tutorial series, or just grab one of the accompanying scene files that are available in each chapter and continue!

    Hi Bjorn, I'm having an issue with my rig at 10:03 when we take the Bones to Curve tool and select our spineCurve then hit enter, my spine does not show up and also when I go down a level in the GEO node that contains the covert node my spine curve looks really weird I have 6 points and the curve loops through 2 times giving me a small loop in the center of my NURBS Curve I'm not sure what to do? I'm using Houdini 17 btw.

    Ok I managed to fix the problem by placing a Blast node betreen the Add node and the Attribute Wrangle node then selecting the offending points that were causing havoc then deleting them muhahahaha!! test my patience will you now Houdini lol
