Creating a Warrior Character: Part 3

by

In part 3 of the "Warrior" tutorial series, Ranjit Rhana will take you through the process of UVMapping the character using Headus UVlayout and Maya, and give you an overview of his sculpting workflow using Zbrush.

Step 1

In this part of tutorial, I'm gonna start with the UV layout of the character, here I'm working with Headus UVLayout for unwrapping, but you can choose any application for it. To start, run Headus UVLayout, click on the "Load" button and select the .obj file we exported from the Zbrush in the last part.

Step 2

Click on the "Display" button, and select "Free" from the window that comes up. Now you'll be able to navigate freely in the viewport of Headus UVLayout.

Step 3

Press "2" on the keyboard. Now since the model is symmetrical I'm gonna turn the "Symmetry" option on, so click on the "Find" button highlighted below.

Step 4

Click on the center segment of the model as shown below. And then press "Spacebar" on the keyboard.

Step 5

Now you'll notice half of the model turns grey in color, now whatever you do on the one side will automatically happen on the other side of the model as well. This function of turning the symmetry ON, only works if model is symmetrical.

Step 6

Now navigate near the neck area and place the mouse pointer on the segment where you want to cut the head, and press "C" on the keyboard. This will cut through the whole loop of the neck.

Step 7

Press "Enter" on the keyboard (make sure the mouse pointer is on the head first,) and the head will separate from body.

Step 8

Using the same technique, cut and separate the head again as shown below and press "D" on the keyboard to drop the mesh into the UVLayout Editor. (Again make sure your mouse pointer is over the part of the mesh you wish to drop, before pressing D.)

Step 9

Press "1" on the keyboard, and you'll enter the UVlayout editor window. Press "Shift+D" on the keyboard and then press "Spacebar", let the UV shell adjust and then press "Spacebar" again.

Step 10

Since we've turned Symmetry on, if you put the mouse pointer over one half of the UV shell and press "S" on the keyboard the opposite half will automatically become symmetrical. At some places where UV's are getting tangled, you can fix them manually by pressing "Ctrl" on the keyboard and moving it using the middle mouse button.

Step 11

This is what you gonna get after fixing the face’s UV's.

Step 12

Using the same techniques separate the other areas of the body according to the UV layout you wish to make for your model. In case of my model, I’ve separated it as shown in the image below.

Step 13

A view from back.

Step 14

This is the result I have in the UV layout editor after flattening the UV's, save the file.

Step 15

One done, Export the model back into Maya.

Step 16

Now in Maya, go to Window>UV Texture Editor to open the UV texture editor.

Step 17

This is what you gonna see in the UV texture editor. As you can see the UV's shells match the result we had in UVLayout.

Step 18

Arrange all the UV shells in the texture page, make sure you don’t have any of the UV shells overlapping and all the shells should be arranged in the upper right quadrant of UV texture editor. Once done, export the model out of Maya as an .obj.

Step 19

And Import it back into Zbrush.

Step 20

Now navigate to the "Texture Map" options in the Tool menu, and click on the "New from UV check" button. Once the model gets imported into Zbrush the UV's gets flipped vertically.

Step 21

Zbrush is gonna check the UVlayout of the model and generate a texture map based on the UVlayout. If you have any problems with the UV's (i.e., overlapping etc.) Zbrush will highlight them in red, as shown in the image below.

Step 22

If you have overlapping, take your model back into Maya and fix the problem there, and then bring it back to Zbrush. Check the UV's again by clicking on "New from UV check".

Step 1 Image

Step 23

Once you are sure your UV layout is good enough, go to "Polygroups" in the Tool menu and click on "Auto groups with UV".

Step 1 Image

Step 24

Zbrush will then create polygroups according to the UVlayout. Now you’ll be able to hide/unhide parts of the mesh by Pressing "Ctrl+Shift" on the keyboard and clicking on the created polygroups.

Step 1 Image

Step 25

Now press "Ctrl + Shift" on the keyboard and click on the face, to start adding details to it. Also press "X" to turn on Symmetry, on the X-axis.

Step 1 Image

Step 26

Select the "ClayTubes" brush and change the alpha from square to circular (Alpha 06). I find ClayTubes, a great brush for defining volumes.

Step 1 Image

Step 27

Keep using the "Smooth" brush (by pressing 'Shift', while using any brush) while defining the volumes. And this is where it’s at after adding some detail to the face.

Step 1 Image

Step 28

Now I’m going add eyeballs to the mesh, select "Sphere3D" from the Tool menu and convert it to "Polymesh 3D". The Sphere will replace the Face model on the canvas.

Step 1 Image

Step 29

So select the Face model from the "Quick Pick" menu to get it back.

Step 1 Image

Step 30

Now from the "SubTool" options in the Tools menu, click on the "Append" button and select the Sphere from the Quick Pick menu.

Step 1 Image

Step 31

Select the "Sphere" from the SubTool menu and click on the "Activate Edit Opacity" button on the tool bar as highlighted in the image below. Now everything on the canvas accept the selected mesh (sphere) will become transparent.

Step 1 Image

Step 32

Select the "Transpose" tool (Move, Scale, Rotate) and arrange the eyeball in the proper place.

Step 1 Image

Step 33

Fix the area around eye.

Step 1 Image

Step 34

Click on the "Clone" button (highlighted in the image below,) make sure the "Sphere" is selected in the SubTool list. Now you’ve created a clone of the selected SubTool in your quick pick menu. Append it using the same procedural as in step 30.

Step 1 Image

Step 35

Now go to "Deformation" in the Tools menu and click on the "Mirror" button, make sure only "X" is highlighted on the button, as shown below.

Step 1 Image

Step 36

Now that you have both eyeballs placed inside the head, start giving the face more detail.

Step 1 Image

Step 37

After few steps.

Step 1 Image

Step 38

Select the "Pinch" brush, this is a very good brush for defining the edges, as in our case for edges of the lips.

Step 1 Image

Step 39

After defining the edges of the lips.

Step 1 Image

Step 40

Using the "Claytubes" brush again, add some strokes for the beard.

Step 1 Image

Step 41

Once you’ve added enough strokes for the beard, select the "Magnify" brush.

Step 1 Image

Step 42

Use the Magnify brush to increase the length of beard, as shown in the image below.

Step 1 Image

Step 43

Detailing on the ear. For continuous, more precise brush strokes you can turn on the "Lazy Mouse" option by pressing "L" on the keyboard or from the "Stroke" menu.

Step 1 Image

Step 44

Press "Ctrl+shift" and click on the canvas. The head will now be hidden and body will appear on the canvas. Start sculpting the body same way.

Step 1 Image

Step 45

These are some of the reference images I’ve used for the body.

Step 1 Image

Step 46

And this is what I got after sculpting more detail on the body.

Step 1 Image

Step 47

Here is a view of the back.

Step 1 Image

Step 48

Here is the result after I did some more detailing on the head.

Step 1 Image

Step 49

For the hair select "Alpha 44 or 45" with a "Standard" brush. Press "L" on the keyboard or turn on "Lazy Mouse" from the stroke menu, and add more detail to the beard.

Step 1 Image

Step 50

Here’s the head after some more detailing.

Step 1 Image

Step 51

And this is what I got by the end of this part of the tutorial.
