I used Rigify to create a rig for a character that I want to animate. I added in a human meta-rig and formed it to fit the human model. The problem occurs when I click generate under the Rigify buttons category. It does not create points for me to manipulate for the fingers, elbows or knees or a full skeleton for the character. Any ideas why?
Armatures have their own layering system - similar to the layers available in the 3dview - only bones on active layers will be visible. Rigify uses these layers to group various related bones together, eg the finger bones are all on one layer, arm.L(IK) bones are on another and so on.
Rigify also creates a panel that is shown in the properties sidebar of the 3dview (N) that has buttons to enable the various bone layers using more useful names. These buttons are just a convenience that relate to the bone layers available in the armature properties.
