I've been trying to use this Duik script for creating IK solvers for a stick figure, and it's not working. According to the tutorial video, I'm supposed to:
A) set up the anchor points and parent the layers appropriately
B) create a controller for the extremety (a hand in this case)
C) select the extremity, up to the root, and then the controller
D) click the Create IK button
I took a video of this and the result has my hand flying off in random directions... anyone know what i could be doing wrong? http://tinyurl.com/ylyd934
Try pre-composing the layers before you add the IK (making sure you re-adjust the registration point, of course). DuIK is very sensitive if you've modified the layers, especially scaling them, prior to adding the IK.
