I've made a quick video with a demo of the Auto-rig script used in the pre production of Alike
The script generate a full rig with ik/fk, auto stretch, spine with stretch, foots with multple pivots. It also can generate individual parts of rigs: arm/spine/leg and combine them later.
I would like to release it as soon as possible, but first I should update it to the last Blender API changes because it was developed for the v2.60
Also, thanks to Alessandro Chagas Machado for the model, downloaded from blendswap to make the video.
