Building a Complete Human Facial Rig In 3D StudioMax, Part 1: Bone Setup & Controlsby Soni KumariTutorial DetailsProgram: 3D Studio MaxDifficulty: IntermediateEstimated Completion Time: 2hUpdated:January 22, 2013
Today we are launching the next chapter in our epic series of character rigging tutorials for 3ds Max and Maya fromauthor Soni Kumari. The series has so far covered everything you need to know about rigging complete characters inMaya with two fantastic, in-depth tutorials Complete Character Rig In Maya & Complete Facial Rig in Maya. Andnow were completing the series for 3D Studio Max.
Building an animation ready facial rig can be one of the most challenging, time consuming aspects of charactercreation. But fear not! This series will walk you through the entire process from start to finish and give you a detailed,in-depth lesson on what it takes to build an intuitive, animation friendly facial rig from scratch using 3ds Maxs built intools.
This tutorial is a companion piece to our previous premium series Complete Human Character Rig In 3D Studio Max,so its recommended that you complete that series first.
Step 1
In this 1st part of the tutorial, we will learn how to create bones and their controls inside the face mesh. Lets start 3dsMax and open the Old Man Face Start.max file which is provided with this tutorial.
Step 2
Now, well start creating the rig for the face. So, with the face mesh selected, go to the Modify panel and turn Off theUse NURMS Subdivision option.
Step 3
With the face mesh selected, go to the Utility panel, click on the Reset XForm button and then click on the ResetSelected button. After that turn off the Reset XForm button.

Well do the same in the Utility panel. With the face mesh selected, first click on the Collapse button and then click onthe Collapse Selected button to collapse the mesh. After this, turn Off the Collapse button.
Step 5
Before we move ahead, we have to arrange the objects in layers. So click on the Layer Manager to open the LayerManager window.
Step 6
So with the face mesh selected, click on the Create New Layer button and then Rename it as Head Mesh. In this waythe face mesh is added into the Head Mesh layer.
Step 7
Click on the Create New Layer button three more times, and then Rename the layers as: Eyes, Tongue and Tooth.

Now we will add the particular objects into their respective layers. So with the Eyes layer selected in the LayerManager window, select both eyes balls in the viewport and then click on the Add Selected Object button which isdenoted by (+) sign. Now the eye balls have been added to the Eyes layer.
Just like this, select the Tongue layer, then select the tongue mesh in the viewport and then click on the Add SelectedObject (+) button.
