🎯 Lesson Quests

🚩 Quest 1: Head Z Movement
🚩 Quest 2: Neck X and Z Movement
🚩 Quest 3: Head Z Augment Physics Group

‍

🚩 Quest 1: Head Z Movement

We'll be using the rotation deformer Head Z Rotation in the hierarchy.

Make sure the Rotation deformer is positioned roughly here on the head:
You can hold CTRL and click the middle of the rotation deformer to move it.
I also like to hold Shift to keep it centered.

Angle Z Augment – Value: 30
Apply your rotation here, then use Reflect Horizontally to mirror it over to Value: -30.

‍

🚩 Quest 2: Neck X and Z Movement

Inside the Neck [XY] Deformer, create two new deformers:

• Neck Z – Head Angle
  
  • Neck XY – Head Angle

Make sure these deformers are centered around the neck properly.

Now create the following deformations:

🔁 On Neck Z – Head Angle

Deform for Angle Z Augment = 30

Then reflect for Angle Z Augment = -30

🔁 On Neck XY – Head Angle

Deform for Angle X Augment = 30

Then reflect for Angle X Augment = -30

💡 Optional:
You could also deform this for Angle Y if your model has neck textures.
This one doesn’t, so it’s okay to skip it.

‍

🚩 Quest 3: Head Z Augment Physics Group

Head into the Physics window, duplicate your Head X or Head Y physics group, and change the input adn output:

• Input: Angle Z
• Output: Angle Z Augment

Adjust your output scale to make sure it reaches 100% when previewing movement.
