Just like everyone else I’m also excited about the new Bbone bending options. The only problem is that it currently doesn’t use widget controls, but numerical values which are less intuitive.
I understood that there might be an intention to make some special widgets for it, but I’ve decided to test it already with a custom widget to control it using something that looks similar to a bezier spline handles.
I used a separate control armature (in order to avoid dependency loops) which is connected to the Bbone options using drivers. It was actually working very straight forward and easier then I thought.
I know that it currently contradicts the idea of “easy rigging”, but this is currently just a “proof of concept”. the next step would be to write a script which automatize the process, similar to rigify’s samples.
I’m not sure if and when I’ll have time for it. but if anyone wants to collaborate on it then the sample file is available to download on my git.
