 +=== Bone Types ===
 +
 +In Edit and Pose modes, under **Data > Viewport Display** you can select different types of bones with the **Display As** option.
 +
 +When selecting **B-Bones** for **Bendy Bones** an additional option menu will appear in the **Bone** tab where you can add segments as well as other options.
 +
 +This is the only Bone type that has this segment property.

 +=== Finger controllers ===
 +
 +The finger controllers can be **''S''** to scale and this will curl the fingers inwards to close the hands.
 +
 +It's good practice to check that the curl doesn't twist and correct if necessary.
 +
 +Correcting twists in fingers can involve editing the mesh slightly if it seems to be slightly rotated the wrong way.

 +=== Rig re-generation ===
 +
 +When re-generating the rig, the new one replaces the old one. The parenting is kept but so are the weights from the previous parenting.
 +
 +If bones were moved, it's best to re-parent the new rig to the mesh with automatic weights to re-generate them.
 +
 +Make sure the rig works perfectly well before going into weight modification.
 +
 +----
 +
 +=== Weight Painting Rigify ===
 +
 +The generated rig creates a set of deform bones which are hidden by default but reference the **DEF-xxx** vertex groups automatically created on the mesh.
 +
 +These deform bones can be toggled visible by going to the **Data > Bone Collection** section under the name **DEF**
 +
 +Then select rig then mesh and go into weight paint mode.
