INTRODUCTION TO RIGGING
In this session, we are going to learn about
 Introduction to bone setup
 rigging character
Bone setup is an important tool of rigging in any 3d software. Bone setup
also known as skeleton or joints are used in the 3d software for creating the
character of the organic rig in the software.

With the bone tool setup, we can easily adjust the size of the bones and
joints according to the mesh.

Other than just creating the joint setup we skeleton tool also provide us with
several other useful tools. They are:-
 Insert joint tool
 Reroot joint tool
 Remove joint tool
 Disconnect joint tool
 Mirror joint tool
 Orient joint tool
Insert joint tool: - with the help of this tool, we can insert an extra joint in
between of pre created joints.
Reroot joint tool: - this tool helps us in changing the root or the origin of the
joint.

Remove joint tool: - this tool helps in removing the joint from the hierarchy
yet maintaining the hierarchy.

Disconnect joint tool:- this tool helps in the discontinuation of the hierarchy.
Connect joint tool:- as the name suggests this tool helps us in connecting
the two different joint setups.

Mirror joint tool: - this tool helps in creating exactly mirror replica of the
joint created.
Orient joint tool: - this tool helps us in setting the orientation of the joint by
setting the LRA or the local rotation axis of the joint.

Creating a rig for the character is another helpful and easy tool that can be
used for better character animation.
The very first thing one does is create the complete rig setup for the body
mesh
We have to create following setups for the complete body rig.
 Leg setup

As we are done with creating bones next we have to start creating attribute
or controllers.

INTRODUCTION TO RIGGING
As we are done with the rig and the controller setting the last thing we have
to do is we do skinning.
Skinning is the process with the help of which we attach bones with the
mesh and divide the weight of the vertices on the rigged bones or joint.
First, we select mesh then bones and then apply bind skin>smooth bind for
applying smooth bind skin on the mesh.

As we ago to smooth bind we can find an attribute drop down menu beside
it. In this menu, we have to apply certain changes as shown in the figure.
Soon after applying the smooth bind we can see that mesh starts working
with the bones.

But the flexibility is not proper for achieving proper flexible skin we have to
paint weight manually that means we have to divide an equal amount of
weight on the bone for the result.
Painting weight is the final process for achieving the complete rigged
character. The painting into the polygons with the help of a brush can be
achieved through the color property. If the paint color will be white then it is
more effective and if the color is being got feded off then it is least effective.
