Copyleft lisence - if you use this script you don't need to credit me :^)
This is a python script I made to speed up my rigging process in Maya. In short, the script automatically creates FK and IK controllers for a chain of joints, and creates a switch that matches the poses seamlessly between the controllers.
This bindpose article helped me a lot with figuring the math behind good pole vector positioning: https://bindpose.com/seamless-ik-fk-switch-maya-python/
Though I used online sources for help, I wrote every line of code myself.
