How to Create a face rig in Blender
This tutorials covers how to create a more advanced type of facial rig, showing you how to use the "stretch to" constraint to give the face a more fluid way of animating. The "stretch to" is great for things like lips and eyelids (which is shown in this tutorial); in addition, you'll see how to make the eyelids "stick" to the eyeball surface, so there's no unwanted gap between the two while animating. Whether you're new to the Blender Foundation's popular open-source 3D computer graphics application or are a seasoned digital artist merely on the lookout for new tips and tricks, you're sure to be well served by this free video software tutorial from the folks at CG Cookie.
