I've had a chance to talk with many LightWave® users
in the past few weeks, and one question keeps
coming up when character animation is talked
about. "What's an easy way to setup the
eyes on my character?". I hope this tutorial
answers that question and also gives you an idea
of quick and easy solutions for animation. Like
to hear it? Here itgoes!


Modeler:

Step 1: Start
with your character model in Modeler. Here I
have chosen to use this foxy lady.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_001

Step 2: What
we need to do is create 3 Weight Maps. For the
first Weight Map select a polygon on the Face
of the model and use "Display/Sel
Connect
" to select all the polygons
that make up the head.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_002
Note: Make sure that no polygons
in the eyes are selected.

Step 3: Choose New From
the Weight Map Pop-up menu located
in the bottom left corner of the Modeler Interface.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_003

Step 4: The
Create Weight Map panel comes up. In the Name field
type in "Head". Keep
the Initial Value checked and
keep the Value set to 100%.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_004
Step 5: Switch the ViewPort
Display to Weight Shade to see
the results.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_006 Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_005
Step 6: Follow the same steps
as above to create Weight Maps for each eye.

Left_eye Weight Map

You should now have the 3 Weight
Maps you need for this set-up. Now We need to
Create 3 Skelegons and we will be ready to send
our Object to Layout.

Step 7: Switch
your Viewport to Right, and
Choose Wireframe as your Display
type.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_009
Step 8: Put Layer 2 into the
foreground and Layer 1 (The Layer with the Head)
in the background.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_014

Step
9:
Using the Skelegon tool (Create/Elements-Skelegons),
create a Skelegon for the Head.


Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_010
Step 10: Switch your Viewport
to Top.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_011

Step 11: Create
2 more Skelegons for the eyes. Place the base
of the Skelegon in the center of the eye.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_012

Step 12: Switch
to Front in your Viewport and
line the Eye Skelegons up with the pupils of
the eye.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_013
To make it easier on ourselves, let's name the
skelegons.

Step 13: De-select
the Eye Skelegons and select the Head Skelegon
(the large one we created in the side view).
Choose "Detail/Other-Rename Skelegon" and
name the Skelegons the same as below:

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_015

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_016

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_017

Step 14: Copy
the Skelegons from the 2nd layer and Paste them
into the first with the Head object.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_018
Step 15: Save your Object and
send it to Layout.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_019
Layout:

Step 16: Now
that we have our object in Layout we need to
Convert the Skelegons we created into Bones.
Choose "Add/Bones/Convert Skelegons
into Bones
". A Dialog box should
come up telling you that 3 bones were
created
. Click OK.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_020

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_021

Step 17: We
need to apply the Weight Maps to the Bones. Choose Bones and
then choose Item Properties to
bring up the Bones Item Properties Panel.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_022

Step 18: Assign
the Bone Weight Map for all
three Bones.
Bone: Head = Head
Bone: Right Eye = Right Eye
Bone: Left Eye = Left Eye

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_023
Select "Use Weight Map Only" for
each Bone as well.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_025

Step 19: Create
a Null object. Add/Objects/Add Null.
and Move it out in front of
the Head Object and Keyframe it
in it's new location.

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_024

Step 20: Set
Each of the Eye bones Target Item to
the null object. This is located
in the Motion Options Panel.
(Item/Motion-Motion Options).

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_026
Your scene should look something like this:

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_027
Step 21: Move the null and
watch the eyes follow!

Tutorials LightWave 3D Animation Basics: Eyes Setup Eyes_028

That wraps up a basic eye setup.
If you want to take it a few steps further, you
can create three nulls instead of one. Have one
null for each eye and have each eye Target a
null. Then have each of the eye nulls parented
to the third null. That way you can move each
eye separately by moving each of the eye Nulls,
or move both eyes by moving the third null. The
image below shows this in action.
