Deformation Reference
Its always good to search for videos before
starting your rig; Sites such as Youtube or
Framepool will help you very much. Remember
to be specific in your search, like adding the
specific area of the body you want to focus on,
for instance: hand, shoulder. Use two different
types of movement and action in the search.

This can help you to see de deformation of
each body area, for example: running, walking,
jumping.
Drawing books are another great source of
inspiration, for both humans and animals. The
explanation of how to paint a human or animal in
different poses and how the shapes change can
be easily translated to 3D. If you are working on
a human character, your own body and a mirror
will be your easiest reference.

Facial Expressions Reference

The way a person shows feelings (such as
happiness, sadness, anger) is mainly by facial
expressions.
The other way of transmitting feelings is the
body language, but this is a job for animators.
As a rigger, you will have to provide them with

Checklist
Rigging is a technical process where you have
to take a lot of things into account. It is very
difficult to remember to check everything, so
using a checklist is the best way. A checklist is
usually a word document or excel file where you
include all the things you need to check once
you finish your rig. You will find a few checklists
in the next chapters.

Software Used: 3ds Max

Chapter Overview
Welcome to the second chapter of the
Introduction to rigging tutorial series for Max.
In the previous chapter we spoke about the
concept of rigging and how to approach a rig,
before speaking about the software itself.
In this chapter we are going to look at the tools
that Max has for rigging. We are not aiming for a
total explanation of each one - Max has a proper
documentation that explains each tool in detail.
Here we will explain the right use and the
advantages of each tool, together with some tips
that will help you when you build your rigs.

It is important to know the difference between

the three systems:

Local: uses the coordinate system of the

selected object, the orientation of the pivot of
that object in particular.
Gimbal: is the way that Max manages the
objects internally in 3D space and is related to
the curves in the Track View, always related
with the parent of each object; we will learn
about it in the next section. (Fig.10 See
Maxscene: 4_Coordinates.max)

Gimbal, Lock and Axis Order
Gimbal Lock is a problem that we have when
we rotate an object in its three axis. The simple
explanation is that one of the axes will always
be parallel to the parent axis. So after rotating
all the axes, two of them will come very close.
There is no way to avoid this problem, in that
case the animator will choose to use local
coordinate system to rotate the object in the
desired direction, but with the consequent result
of moving the three curves at the same time.

Controllers
Max uses controllers to manage the movement,
rotation and scale of the objects. There are
many of them but we are going to concentrate in
the ones most used in rigging.
To change or apply a controller you can do it in

Float List Controllers

A float list can be applied to position, rotation,
scale, or to a single controller. (Fig.21)
A float list is one of the most powerful features
that Max has for rigging. The concept is easy
- you usually have one controller to manage
position, rotation or scale; the float list allows
you to add more than one controller to manage
them. This ability of having several controllers
has many advantages in complex rigging.
You can assign the float list with the Track View
or in the Command Panel Motion.
Once you have assigned a float list, you can
select the available channel and assign a new
controller. Every time we add a controller an

The following images show a sphere linked to
a point. We want to change the property radius
of the sphere, but we dont want to select the
sphere to do so, so the easiest way is to add
a custom attribute to the point with the radius
and connect this parameter to the radius of the
object sphere by using wiring. (Fig.55 56)
We can use the point to move, rotate and
scale the sphere, and by means of the custom
attribute we can change the radius of the
sphere, so all the controls stay in one object
only.
Custom Attribute helps to add parameters to an
object and manage lot of things by editing only
one object. Simplicity is a must in rigging.

Morpher
We will use this Morpher mainly for facial
animation. We can model different expressions
and use it to animate each one. We can have a
hundred different expressions loaded. (Fig.60)
The image above shows a morpher that we
use to move the brows up and down.
Note: we can animate in the morpher modifier,
but to keep things simple we normally create a
spline with custom attributes and connect it
with the morpher with wiring. It avoids having to
select the mesh to do facial animation. As we
mentioned in chapter one, a good practice is
having all the controls of the rig as splines

Skin
Skin is the modifier we use to make our meshes
deform with the rig. Is a complex tool with a
few sub-tools as Weight Editor or Weight Tool,
Symmetry, etc. We can add as many object as
we want to deform the mesh and we can tell
how much this object will affect each vertex.
(Fig.61 62)
There are two ways of weighting: True
Envelopes and Vertex Weighting. We normally
use a combination of both.
Envelopes (Fig.63)
Vertex Weight (Fig.64)

www.3dcreativemag.com

page 105

Issue 057 May 2010

Chapter 2: Knowing your Tools Introduction to Rigging

Envelopes: each object has an envelope that we
can modify making it smaller or bigger and it will
influence each vertex it has inside. Envelopes
are normally used for a quick skin or to start the
deformation.
Vertex Weight: it edits each vertex and tells
what object or objects are going to be driven the
vertexs position.

Skin Morph
Normally we make a good skin that would
work in 80% of the poses, but in some extreme
poses we need to define the deformation a bit
further. To do this we use Skin Morph.
Skin Morph works on top of skinning and we
can model to correct the mesh. Each morph
gets launched by the rotation of an object. The
correction will be working 100 % when the angle
of the rotation is equal to the one we setup,
and it will fade off when the angle is not the one
setup for the correction.
With this way of setting up the correction will
happen when we are in the desired pose only.
(Fig.65 66)
The images show the difference between having
skinmorph or not. We used skinmorph to correct
the shape of the elbow.

Maxscript:
Maxscript is the script language of Max, and it is
used to code.
To work with Maxscript we use two main tools the Listener and the Editor.
Listener: used to quick scripts, small tests and
read the MacroRecorder.
MacroRecorder is a useful option that records
maxscript command when we use Max and it is
a good way of starting to read code.
Editor: saves and loads maxscript and allows
editing more than a script at a time. Useful once
we start making our own scripts. (Fig.77 78)

Facial Rigging and Scripting

The aim of these tutorials is to show and explain how you might tackle rigging your 3D
character for animation. These tutorials will give help and advice to novices and experts
who are looking to build on their rigging skills or approach rigging for the first time.
The series gives a detailed step by step guide as to how to approach rigging but also
shows us how to tackle common problems and issues that regularly occur even in a
professional environment. The artists will be reflecting on working in the industry as well
as talking us through their individual approaches to creating the best rigs possible.

Using the naming convention described in the
first chapter we will be sure the layer _mesh
exists and the objects are inside.

For the spine we will use 5 bones. In reality, the
spine has 38 or 39 elements but we simplify it
in rigging. The hips consist of one bone. Again,
that body area has more bones but simplification
is better. We place the bones closer to the back
of the body, where the spine is in reality.

5.2 Controls
Pelvis
This is the main controller for a spine and if we
move it the rest of the spine will follow. It is
the first control that animators start to animate.
When you move and rotate it, the spine, arms,
neck and head follow. (Fig.11 + Fig.12)

Spines
We have two spine controls and by rotating
them we can achieve a lot of the desired poses
for the upper body. (Fig.13 + Fig.14)
Independent Hips
A lot of the time we want to rotate or move the
hips without affecting the rest of the spine or
upper body. That is why we have independent
hips. (Fig.15 + Fig.16)
Independent Chest
We have a similar case with the chest.
Sometimes we like to move or rotate only the
chest without affecting the other parts of the
spine. (Fig.17 + Fig.18)

We have two controls for the head and neck.
Neck
(Fig.48) The neck control can be rotated in
any direction and makes the bones of the neck
rotate. The 4 bones of the neck react to the
rotation of the neck base making a nice curve.

Head
(Fig.50) The head control can rotate and move.
It is important that we can rotate the head
separated from the neck. (Fig.51)
When we move the head control sideways and
back and forward, we can achieve nice poses
that we cant achieve with rotation. By moving
the head control up and down we stretch the
neck. (Fig.52)

Because we havent yet rigged the legs and

Facial Rigging and Scripting

The aim of these tutorials is to show and explain how you might tackle rigging your 3D
character for animation. These tutorials will give help and advice to novices and experts
who are looking to build on their rigging skills or approach rigging for the first time.
The series gives a detailed step by step guide as to how to approach rigging but also
shows us how to tackle common problems and issues that regularly occur even in a
professional environment. The artists will be reflecting on working in the industry as well
as talking us through their individual approaches to creating the best rigs possible.

3.2 Controls
For the leg controls we have to have a
difference between IK and FK, and we will use
an attribute to blend in between both.
FK
Only rotating objects can achieve the desired
poses. We will have FK controls for the thigh,
calf, foot and toes (Fig.24).
IK
The main control in the IK system is the IK
control for the foot to move and rotate it. We can
change the position of the leg and foot. It has
attributes to control the rolls for the foot and a
parameter for changing from FK to IK (Fig.25).
The other control is the IK swivel target, which
means the knee of the left leg will always be
looking at the control. We use this control
together with the IK main control (Fig.26).

3.3 FK /IK three chains system and

two chains system.
The normal setup a lot of people use is the three
chains system - one chain is FK, a second chain
is IK and a third chain blends between FK/IK
(Fig.27).

The aim of these tutorials is to show and explain how you might tackle rigging your 3D
character for animation. These tutorials will give help and advice to novices and experts
who are looking to build on their rigging skills or approach rigging for the first time.
The series gives a detailed step by step guide as to how to approach rigging but also
shows us how to tackle common problems and issues that regularly occur even in a
professional environment. The artists will be reflecting on working in the industry as well
as talking us through their individual approaches to creating the best rigs possible.

Welcome to the fifth chapter of the Introduction

previous chapters we rigged the spine, neck,
head, eyes and legs of the character. In this
chapter we are going to continue with the

and fingers.

if you need to edit where the bone is, use the
bone tool mode edit pivot point.
Now check the bones are centred in the middle
of the mesh for each view. Be sure that the
shoulder, upper arm, forearm and hands are
properly placed for all the views (Fig.04 05).
3) Rename the bones, starting from the
shoulder: Alien_L_Arm_Shoulder__BH,
Alien_L_Arm_Upper__BH, Alien_L_Arm_Fore__
BH, Alien_L_Arm_Hand__BH.
4) Now create the bones for the other side: the
right arm. We could do them manually but it will
not match the other side perfectly. So instead,
use the Symmetry tool. Before using this tool,
make sure the coordinates are in the world
setting and the coordinates for manipulating the
object are in the centre. By doing this the mirror
will happen in the world setting.
Mirror the X coordinates and make a copy. The
Max Symmetry tool works by creating negative
scales that are not good for rigging, so we use
the bone tool options Reset Stretch and Reset
Scale for the new objects.
Remember to rename the bones to R_. To do
this use the IMR DialogName with the copy and
paste inverse (Fig.06).

properly for both arms; we can use the options
for mirror weight so once we have one side
weight properly we will mirror the other side. For
a quick start, I recommend weighting each area
100 that you think will follow a bone; when two
bone areas meet another bone, weight 50 to
one bone and 50 to the other (Fig.23).
We will skin all the fingers for the hands now
and later we will skin them to the finger bones
when we build the rig for the fingers (Fig.24).
Open Maxfile: 3.4_Alien_Arm_skin_01.max to
be at this stage.
Once you have the base skin, create poses for
testing the skin. Use the rig in FK mode as it is
easier to pose the desired poses. Create poses
for each FK control to see how the skin reacts.
Each pose is 10 frames after the previous pose.
Test only one control at a time, so we can locate
the deformation. I prefer this system as it means
we wont forget to skin for any possibility. Having
a few controls moved at the same time can
make the tweaking of the skin a bit confusing.
Note: A good practice is to key all the controls in
each pose to avoid strange in-between poses.
We can do regular procedures, or we can select
all the controls at the desired frame and using
IMR key tool with the option KeyAll put a key
in each control object in each controller (Fig.25
28).
Once you have created all the poses, tweak the
skin.

1) Place the bones in the right place for each
finger. Start in front view and later use the Bone
tools to move the bones and be sure their pivot
is in the right place. Place the joint a bit higher in
the profile of the finger because the deformation
will work better.
Note: The placement of the bones for the fingers
is quite tricky, so pan the views and be sure it
is right in all the angles you can check (Fig.35

Checklist for hand Rig

Before we move on to another part of the rig it
is good to do a checklist for rigging. There are
always too many things to remember to check.
Using this checklist will make things easier.

Facial Rigging and Scripting

The aim of these tutorials is to show and explain how you might tackle rigging your 3D
character for animation. These tutorials will give help and advice to novices and experts
who are looking to build on their rigging skills or approach rigging for the first time.
The series gives a detailed step by step guide as to how to approach rigging but also
shows us how to tackle common problems and issues that regularly occur even in a
professional environment. The artists will be reflecting on working in the industry as well
as talking us through their individual approaches to creating the best rigs possible.

Chapter Overview
Welcome to the sixth and last chapter of the
Introduction to Rigging Tutorial Series for Max.
In the previous chapters we rigged all the
character body parts, so now it is time to rig
the face and create a nice UI for the animator
to work with. With this done, we will have the
character fully rigged.

versions if needed.

For the tongue we will use four bones to

properly deform the mesh and achieve the
desired shapes (Fig.03).

Controls
For the animation of the face well use a
combination of FK controls that we can
manipulate on top of the mesh and a face mask
to drive the morphs.

Jaw
A control we can move and rotate and the teeth
and tongue can follow (Fig.04).

Chapter 6: Facial Rigging & Scripting Introduction to Rigging

Lower Teeth
It is always good to be able to move and
rotate the teeth if is needed for a desired pose
(Fig.05).

Tongue
The best way to animate the tongue is by using
a FK chain of controls - the tongue will follow the
jaw movement (Fig.06).

Face UI
I prefer a nice UI that makes animating easier,
so the UI we are going to use is a mask to
select controls for the eye brows, jaw, lips and
lip corners so you can animate them as you
would move them in reality (Fig.07). So if you
grab a lip corner and move it on the side it will
move the corner of the mouth to the side. I like
each icon to be quite graphic so the user is not
confused by what he is grabbing. I prefer this
kind of face rig instead of custom attributes with
a long list of attributes. This is much quicker way
of animating, and much easier to manipulate.

Axis Order For the controls

Now we have finished the setup of the rig we will have to change a few
axis in order to make the animators life easier when they rotate the
controls and when they edit the curves in the Trackview. We will do the
changes in axis order in the motion panel and remember to be in gimbal to
test what is the best axis order. We will test the best combination to have
as much gimbal lock as possible (Fig.32).
We will change the next rotation axis orders:
1) Alien_L_Arm_FK_Upper__SA and Alien_L_Arm_FK_Upper__SA with
rotation axis order ZXY.
2) Alien_L_Arm_FK_Hand__SA and Alien_R_Arm_FK_Hand__SA axis
with rotation axis order ZXY.
3) Alien_R_Fingers_Index01__SA, Alien_R_Fingers_Middle01__SA ,
Alien_R_Fingers_Little 01__SA Alien_L_Fingers_Index01__SA, Alien_L_
Fingers_Middle01__SA , Alien_L_Fingers_Little 01__SA with rotation axis
order ZYX.
4) Alien_L_Fingers_Thumb01__SA and Alien_R_Fingers_Thumb01__SA
with rotation axis order ZYX.
5) Alien_L_leg_FK_Thigh__SA and Alien_R_leg_FK_Thigh__SA with
rotation axis order ZYX.
6) Alien_L_Leg_FK_Foot__SA and Alien_R_Leg_FK_Foot__SA with
rotation axis order ZYX.
7) Alien_C_Jaw__SA with rotation axis order ZYX.
Open Maxfile: 2.3_Alien_FaceRig_12.max to be at this stage.

Preparing the rig for the animators

The last thing to do is to protect the objects in the hidden, mesh and proxy
layers from being transformed, selected or animated.
We can do this with locks and freeze. To animate them we can setup the
controllers to not be keyable.
Note: Please be sure you are using the latest version of IMR_
Doing one object after the other will take a really long time, so we have

page 60

Issue 061 September 2010

Introduction to Rigging Chapter 6: Facial Rigging & Scripting

for actions in the maxscript. If you want to secure your rig you could go
for all the controls and lock the controllers that are not keyable. A good
maxscript exercise will be to modify IMR_AutoProperties.mcr to do locks
in Trackview too (Fig.34).
When we have locked the objects the last thing we need to do before we
give the file to the animators is delete the objects in the layer Morphs_
layer and delete the layer itself. Morph targets need to be in the scene if
you want to modify them. You usually use them when you are tweaking
the rig but when we pass it on to the animator they dont need them so it is
better to erase them.
Be sure to delete all the selection sets we have created when we were
working. With all this done we will have a clean rig to give to the animators
ready for production.

Conclusion
We have finished the introduction to rigging, and
we have learnt how to apply the main concepts
to create a good rig.
The final rig is a proper rig that has all the
options that the animator will need, making it
easy for him to work with.
We have learnt the power of a good naming
