Blender - define, use and set drivers

Drivers is one of the most powerfull feature of Blender. Unfortunately it is oftenly overlooked, especially by beginners because the interface and the bunch of options available are not self explainatory.

I’ve tried to make a video as simple and as accurate as possible to fill a part of this void.
They are also cool features for more advanced users of blender.

Hope you’ll like it.
