Stage 3 - Eyeball XY & Physics

STAGE

🧭 Lesson Objective

1️⃣ Make the eyeballs move in the X & Y axis

2️⃣ Create physics parameters for the eyeball parts

3️⃣ Add physics to all the eyeball parts

🎯 Lesson Quests

🚩 Quest 1: Make the eyeballs move in the X & Y axis
🚩 Quest 2: Synthesize the eyeball corners and fix their deformations
🚩 Quest 3: Create physics parameters for each eyeball part
🚩 Quest 4: Add physics to each eyeball part

🚩 Quest 1: Make the Eyeballs Move in the X & Y Axis

We’ll be using the following deformers and parameters:

🧱 Deformers:

  • Iris [XY]
  • Pupil [XY]
  • Eyeball Lines [XY]
  • Blob [XY]
  • Highlights [XY]

🧩 Create New Parameters:

  • Eyeball X Augment
    • Min: -1 | Default: 0 | Max: 1
  • Eyeball Y Augment
    • Min: -1 | Default: 0 | Max: 1

After creating these parameters:

At Value 1 of Eyeball X Augment, deform:

Iris [XY]

Pupil [XY]

Eyeball Lines [XY]

Blob [XY]

  1. Use Palette Menu > Reflect to mirror these to Value -1

Repeat this process for Eyeball Y Augment, but deform everything up/down

Iris [XY]

Pupil [XY]

Eyeball Lines [XY]

Blob [XY]

Again, use Reflect to mirror **VERTICALLY!!**

**Don’t forget to apply the same X and Y deformations to your Highlights [XY] deformers**

🚩 Quest 2: Synthesize the Eyeball Corners and Fix Deformations

Now that the eyeballs move left, right, up, and down — we need to clean up the corner positions (diagonals).

🔗 Link Parameters:

Click the link icon beside your X and Y parameters to combine them.

This will show a 2D grid of values (e.g., -1 & -1, 1 & 1, etc.)

When you go to a corner position, it’ll likely look off. Instead of deforming manually, we can auto-synthesize the starting point:

✨ How to Synthesize Corners:

Select all the deformers (Iris [XY], Pupil [XY], etc.)

Click both parameters to highlight them

Open Palette Menu > Synthesize Corners

Confirm and press OK

Now clean up each corner with the brush tool or other deformation tools.

Still looks a little bit off ^

Move the parts around a little bit more to make them look a bit better at the corners! ^

💡 Tip: You can Reflect corner motions horizontally or vertically afterward for symmetry.

🚩 Quest 3: Create Physics Parameters for Each Eyeball Part

You’ll need the following Blend Shape parameters for both Left and Right Eyes:
(Min: -1, Default: 0, Max: 1)

👁️ Eyelash:

  • EyelashL 1
  • EyelashL 2

🔵 Iris:

  • IrisL PH 1
  • IrisL PH 2

🔘 Pupil:

  • PupilL PH 1
  • PupilL PH 2

⚪ Eyeball Lines:

  • EyeballLinesL PH 1
  • EyeballLinesL PH 2

🟣 Blob:

  • BlobL PH 1
  • BlobL PH 2

✨ Highlights:

  • HighlightsL PH 1
  • HighlightsL PH 2

🚩 Quest 4: Add Physics to Each Eyeball Part

Now we’ll add physics motion to each eyeball component using their [PH] deformers and the blend shape parameters created above.

🧱 Eyeball Physics Deformers:

  • Iris [PH]
  • Pupil [PH]
  • Eyeball Lines [PH]
  • Blob [PH]
  • Highlight 1 [PH]
  • Highlight 2 [PH]
  • Highlight 3 [PH]
  • Highlight 4 [PH]

🔧 Example: Rigging Iris Physics

➕ Step 1: Deform Output Shapes

  • Iris PH 1 → Value 1: Stretch Horizontally
  • Iris PH 1 → Value -1: Squish Horizontally
  • Iris PH 2 → Value 1: Stretch Vertically
  • Iris PH 2 → Value -1: Squish Vertically

Repeat similar deformations for each [PH] deformer and parameter.

⚙️ Step 2: Add Physics Group

  1. Go to Modeling > Physics Settings...
  2. Click Add... → Name the group (e.g., "Iris L PH")
  3. In the Input tab, add your movement parameter (e.g., Eyeball X Augment)
  4. In Pendulum settings, choose a double pendulum and Import
  5. In Output tab, add the output parameters (e.g., IrisL PH 1, IrisL PH 2)
  6. Ensure to Increase & Decrease Output to make sure Output = 100%
