Adding more Avatar masks

In the last section, we used a mask to blend in a different leg animation. Here we will create more Avatar masks to use the two walk sequences together to create more variations:

1. In the Project panel, click the PACKT_Masks folder to view its contents in the Assets panel.

   The folder contains two additional Avatar Masks: z_Arms and z_HeadChestHands.

2. Select the new masks one at a time by clicking them in the Assets panel to see how they are set up:
   • For z_Arms only, the arms and hands are highlighted in green
   • For z_HeadChestHands, everything except the head, chest, and hands are masked

3. Click the PACKT_Controllers folder in the Project panel.
4. Select the asset ch5_3_1 and duplicate it using the keyboard shortcut Ctrl + D (Cmd + D if working on a Mac).
5. Select zombie_m2 in the Hierarchy panel.
6. Drag the controller ch5_3_2 into the Controller field beneath the Animator...
