do it now, the UVs will overlap. What we will do is separate the UVs before we combine
them.
1. First of all, separate the UVs, moving them apart.
2. Combine both sides of the geometry making up the hair, welding the vertices down
the center. With the left and right UVs now separated, we can work on them more
easily.
We want to join the UVs across the top of her hair. Connecting them at the part
will mean we can keep the flow of the hair while making sure the detail is not
broken. So, we need to rotate them.
3. Select the UVs for one side of the hair and go to Polygons > Rotate UVs, opening
up the options. Here you can specify what degree of rotation you wish to apply.
4. Rotate both sides until the tops are facing each other ( Figure 8.61 , left).
FIGURE 8.61 Rotate the UVs for the hair; then sew the facing edges together.
5. Use the Sew UVs tool to connect the edges down the center ( Figure 8.61 , right).
6. With both pieces of the hair connected now, edit the UVs a little more before mov-
ing on. Your goal is for the outer hair layer to look like that in Figure 8.62 .
