Tip: Updating the IK/FK Script for API Changes

In this quick Blender 2.5 tip we’ll update our Python script from the ‘Creating an IK/ FK Rig’ tutorial to work with the latest builds (r35270) after a slight API change.

What is covered in this tutorial:
– The API change introduced in later revisions.
– Registering classes so they can be used.

    Tank you very much, Patrick! And once more about FK/IK snapping. This is a wonderful feature that allows to swich easily between fk and ik and vice versa. There are some enthusiasts who want to implement this feature in Nathan Vegdal’s rigify system. I ask everyone to see Nathan’s post: http://blenderartists.org/forum/showthread.php?t=210101. And join us, please, if you want.

    This might sound dumb (I’m a beginner) but why would someone want to update an API script? Or IK whatever script?

      The Blender python API changed since the tutorial for the IK script was released. The change made the previous script not work. The update is necessary to make the script work again in the lastest builds of Blender.

    So Patrick, a question (could not find any other way to contact you). Do you have any experience writing your own nodes for the compositor? I would like to have a random value generator and it should not be that hard to do if you know the general framework. However, I cannot find any documentation on this.
