Few weeks ago, I saw a post from JiriH that explained how to make a seamless Ik/Fk switching : there was a lot of things to do to completely hide the transition during switching.
I worked with JiriH on a python script to make all the steps automaticaly.
Here is the mechanism of the script :
Select the slider you want to move, and press <Shift+LMB> : the script switch the IK/FK mode without transition (leg or arm remain in place during the slider movement)
We wanted this script to be really useful for an animator, so there is an other way to use it : press the ‘O’ key to turn on an «autokeyframe» mode. In this mode, every time you use <Shift+LMB> on a slider, the script will insert every usefull animation keys at the current frame to avoid transition in the animation.
We write the script to be easily adaptable to any character : You just have to change the name of the bone in the beginning of the script, and that’s all.
I would be happy to hear what you think of this work…
