Rig On The Fly v1.0 is finally out after a year of development.
For those who missed it, Rig On The Fly is an open source blender add-on that helps create animations more efficiently. It does so by giving the rigging power to the animator. The idea is simple, automatically create a small modular rig, animate, bake to skeleton, remove the created rig and repeat. No more need for counter-animation or monolithic rigs. You simply rig the part you are working on.
