The great Brian Green, who worked at Pixar as a character supervisor, defines rigging as “Rigging is the process of providing control to a digital model”.
Cutting a long story short, today, in this concise guide, we’ll walk you through the whole process of 3D rigging in animation.
That’s not all.
We’ll also expand our discussion on tools. You’ll learn which of the best 3D rigging software you should consider using to make your work easier.
On top of that, we’ll also gain a deep insight into the career of a 3d rigging artist (Complete roadmap included below).
So, without further ado, let’s get started.
What is 3D Rigging?
Let’s first start with the basics. Rigging is commonly known as making the skeleton animation. Basically, it’s a technique that defines the range of gestures and actions of your 3D character.
Rigging isn’t only for human models; you can rig any object with an action. This is the most important consideration. Rigging artists use a sequence of linked bones to get this effect. The galaxy, skyscrapers, and even the Pixar lamp are some of the earliest instances of rigged 3D models.
Let’s take a look at where you can see how 3D rigging looks like in a 3D animation:
3D Rigging Process: How to rig a 3D model?
TThis might be a little technical stance for you to understand, so pay close attention to this part. The process of 3D rigging is pretty complicated, which makes it difficult to comprehend.
So, for your ease, we have divided the 3D rigging process into four main parts:
1. Mesh/Skinning:
This is the step where you do the wireframe for your 3D model. You as an animator will start creating characters with a 3D mesh.
What’s a 3D Mesh?
A 3D mesh is a structural build of your object using a collection of polygons and vertices. It serves as a wireframe to start with the rigging process.
What happens in 3D skinning?
A 3D rigging artist creates and sets all the bones and joints of the model. Once it’s done, the skin meshes to the model’s bones. All these together represent an armature.
Know that to create the mesh structure for your model, you can use any of the three techniques:
- Spline Modeling
- Polygon Modeling
- Sculpting
2. Creating Controllers:
The second step is to create controllers. You deploy controls with geometric shapes to assist animators in understanding movement of every part of the body.
Some of the geometrical shapes you can use for controllers are:
Diamond:
It facilitates the model’s rotation and translation. Particularly used in model’s hands, feet, and the central part.
Cube:
The cube acts as a translator of controls.
Sphere:
The sphere is used to facilitate rotation. The pelvis, neck, and torso are the areas where the sphere is used.
Trapezoid:
Trapezoid makes the joints. The knee and elbow are the two most common areas where the trapezoid is used.
Your skeletal design process is now complete.
What’s next?
Now the artist will add the model’s movement and facial expressions. Every movement has a hierarchical link between the bones, much like a parent and kid.
Shoulder movement in 3D rigging
In a 3D model figure, shoulder movements also affect the hand and forearm bones. This way, character rigging is easier since the rigger doesn’t have to describe actions for each aspect of an object.
3. Making Joints:
The third step involves making joints.
Know that these differ from the kind described in the first step of this process. A key concept to master here is weight painting.
Using a weight scale for every part, you’ll learn how each component of the 3D model interacts with others. This means how much weight is exerted on each bone by the other in the body is key to the model’s ability to move in a more realistic and natural way.
Similar to Blender’s auto-weight-painting feature, other software packages include one as well. Based on the notion that most characters follow the same intricate pattern of the human skeleton.
However, the weight of each bone must be tuned for optimum 3D rigging.
4. Forward and Inverse Kinematics:
Hierarchy exists between the bones, as previously stated.
To understand hierarchy better, check out two important concepts below:
Forwarding Kinematics
These are movements in the upper part of a model that also moves the bottom part.
Inverse Kinematics
These are movements in the lower part that happen independent of the upper part. So, the animation process for inverse kinematics may be easier as you’ll only need to animate the lower part.

Character Rigging Artist: An insight into the profession
As part of the animation process, 3D computer-generated (CG) models are used to create the skeletal structure for the character, which is then animated.
Modelers create the characters, while riggers put them into action.
Animators put rigs to the test after creating the skeleton and movement network. After the animator makes the final edits, the rigging part will be completed.

3D Rigging: FAQs
- What is 3D animation model rigging?
3D animation model rigging involves producing a digital skeleton, also referred to as “rig”, for a 3D character or object. Rigging allows artists to control movement by maneuvering virtual joints and bones. So, whenever you see a 3D animated character dancing, jumping or moving, know that it’s the work of rig. Without a rig, the character would be static and unable to move.
- Who is a 3D rigging artist?
A 3D rigging artist is your technical animator, or technical artist, responsible for producing 3D virtual skeletons for computer-generated (CG) characters and objects.
- Which software program is best for 3D rigging?
According to most rigging artists from the industry, Autodesk Maya is hands down the best software program for 3D rigging. This tool offers you an extensive variety of features to perform professional-level character rigging with a high degree of customization. It is easily the tool of choice among many animation studios and game developers.
