Edit: Forgot to add link to github https://github.com/gnastacast/bendy_bone_handles
Yet another blender add-on to add a new bendy bone object with handles. Several these have been made, most don’t work with 2.8 any more. This one does. It adds a bendy bone as a new object in the same way you would add an armature. Support coming soon for being able to add handled bendy bones into existing armatures in edit mode. For now just arrange them and join them in as you go. Tested with 2.80 and 2.81. Includes all the drivers needed for scaling both ends of the curve and changing the weight of each handle sort of like a bezier. The last version I saw of this was https://www.youtube.com/watch?v=qYs3En7ihL0 but now it says DO NOT BUY right on the site so I made another.
Here is a video of it working
