Separating out the hair

Depending on the complexity of the scene and rig, you may find you want to animate the hair in its own layers, especially as we introduce more behaviors into the mix. This means we will need to go back to the rig and ensure the hair is isolated for the three head phases. To do this, see the following:

1. In Photoshop, start at the top of the layer list. In this case, expand 3/4th Head and click Background.
2. You can select the hair in a variety of different ways. The quickest may be to use the Magnetic Lasso Tool option (cycle to it using L on the keyboard):

3. Click once and drag along the edge of the hair. The magnetic function should snap to the outline. If you need to add a point manually, simply left-click.
4. Keep dragging until you’ve selected all the hair. If a point gets added by mistake, you can move a step backward...
