Rigging: Armatures and Bones for Character Animation

Chapter 5's own tip box pointed here directly: this chapter shifts focus from a model's own visual appearance toward giving it the ability to move and pose convincingly. Rigging builds exactly that capability, using an Armature and its own bones to control a mesh through poses rather than moving raw geometry directly.

What Rigging Actually Solves

Blender Fundamentals' own Chapter 8 keyframed an object's own whole-object transform — position, rotation, scale — but a character needs its arm to bend at the elbow while the rest of its body stays still, something a single whole-object transform simply can't describe. Rigging solves this by adding an internal control structure specifically built for posing individual parts of a mesh independently.

The Armature: Blender's Own Skeleton Object

An Armature is a distinct kind of object, built specifically to act as a mesh's own internal skeleton — invisible in a final render by default, existing purely to control how the character's own mesh deforms and poses.

Bones: Building a Hierarchy

Individual bones inside the Armature are arranged in a parent-child hierarchy — a hand bone parented to a forearm bone, parented to an upper-arm bone, parented to a shoulder bone — the same underlying parent-child relationship Chapter 3 of Blender Fundamentals covered for whole objects, applied here at a much finer level within a single Armature.

Parenting a Mesh to an Armature: Skinning

Skinning parents a character's own mesh to its Armature, so moving or posing the Armature's own bones deforms the mesh's own geometry to follow along, the same way real muscle and skin follow a real skeleton's own movement.

Weight Painting: Controlling How Much Each Bone Influences the Mesh

Weight painting assigns each vertex a value describing how strongly a specific bone influences its movement, painted directly onto the mesh's own surface like a heat map — a vertex near the elbow might be influenced heavily by the forearm bone and only slightly by the upper-arm bone, blending smoothly across the joint rather than creating a hard, unnatural break.

Posing: Moving Bones to Animate the Mesh

Once skinned and weight painted, Pose Mode lets individual bones be rotated and positioned directly, deforming the character's own mesh to match — an arm bending at the elbow, a hand gripping an object — and these poses can then be keyframed exactly the way Blender Fundamentals' own Chapter 8 keyframed a whole object's transform, just applied to individual bones instead.
