4. You can now start polypainting into the active area. You can use SpotLight or ZAppLink
   for this process. Figure 5.65 shows polypainting into HD geometry. The jagged line
   on the upper arm is the border of the active HD region. Notice the difference in the
   color texture resolution when HD is off (Figure 5.66).

Figure 5.65 Polypainting into the active HD region

When you are done painting the active HD
region, hover the mouse over the background and
press A. This will exit HD mode. You will see your
colors become soft again—the color resolution is still
there but only visible when rendering in HD. You can
now hover your mouse over another area and press A
to enter HD mode. As we saw in Chapter 4, you will
need to work your way around the whole model in
overlapping HD regions building up the color texture.

Extracting Maps from the HD

There are two methods of extracting the HD color
information into a texture map that can be exported
to other software. Both approaches require that the
mesh have UV coordinates assigned.

HD Standard Polypaint

Figure 5.66 Compare the resolution between polypaint and

polypaint in HD. The fine texture of freckles and pores is

more apparent on the left side of the image where HD is used.
