In part three of my scorpion rig series, I went into some detail of how I make a spline IK stretchy. The approach is something I’ve used for a while and I’ve made a Python script a while back to automate the process. Today, I wish to share that script with the world! How it works is that it takes the specified Spline IK,  builds the nodes, and connects the network together to make a stretchy system. You can download it here; give it a try, and feel free to post any feedback!
