Rig: Animator Skeleton & Viewport
Structure a hierarchy defining how the parts of your Asset will move and rotate in relation to each other during editing and when adding motion.
What Are the Skeleton Panel and Viewport?
The Skeleton Panel displays the structure of your compound or animated asset's rig, while the viewport displays models linked to each part of the rig, called a node, and allows you to change the position and rotation of each model/node to pose your rig and create motion keyframes in animations.
What is a Rig?
A rig is a combination of multiple models to shape a compound asset (static) or an animated asset and define how the models may move in relation to each other.
The relationships are set up in a hierarchy of parent and child nodes in the Skeleton Panel, where movement of the parent node determines the movement of its child nodes. A child node can also be a parent of other nodes, making it possible to rig and animate complex entities.

Node Menus
First, let's look at how the skeleton panel displays node menus.
Parent and Child Relationships
Child Node
A child node is attached to a parent node within the skeleton hierarchy. This empty node controls the location of any attached model relative to the position of the parent node.
Bounding Box
When you create a new node, it will display as an empty bounding box of 32x32x32 (if bounding boxes view enabled) until a model is linked. Then the bounding box will match the model linked to the node.
Motion
If the position of the parent node is adjusted, the child node will follow. However, the child node can be moved independently of the Parent.
The exception is when Inverse Kinematics is togged on in the Top Bar, where the child node can be positioned and its parent (as well as its parent, and so on) will follow, which helps when it's more natural to position the child node at the end of chain of influence created from a hierarchy with multiple levels.
Managing Nodes
Add a Child Node
Click on the three dots button to the left of the node you wish to add a child node to and choose "Create Child Node" from the menu.
There will then be a prompt asking for the "Name of new Node." Type your preferred name and press the ENTER key.
You can use this same process on the newly created node to give it a child node of its own. This creates a chain of influence where the newly created child will treat the previously created child node as its parent, but will also follow the influence of the parent of its parent node.
Try to create and use a clear naming convention for new nodes and models.

Managing Hierarchies of Nodes
Building a Rig
To create a rig, first you must first decide the shape of your whole entity.
Then you will break it down into smaller parts, or models, based on the necessary structure, whether it is static or animated.
To move these parts, nodes must be added in the Skeleton Panel in a hierarchy of parent and child relationships.
Nodes are sometimes called the "bones" of the "skeleton."
Models are linked to each node with a simple drag and drop from the Library to the node. Then they are positioned by selecting tools in the Top Bar and adjusting in the Viewport. Be sure the pivot point for each model is positioned correctly for the expected motion.
Example:
The pivot point on the lid of a chest should be on the back where the hinges would be.
You can create multiple animation states in the Timeline panel, which are poses of your rig's nodes/models. For each animation state, you can add motion keyframes to make the nodes/models move.
