Figure 7.70
An image file is
mapped to a NURBS
plane and a NURBS
sphere. Notice the
locations marked in
the image and how
they map to the
locations on the sur-
face, with the pixel
coordinates directly
corresponding to
the surface's UV
coordinates.
Working with the A Panels
This section assumes that you have some working knowledge of Adobe Photoshop. You can
skip the creation of the maps and use the maps already on the CD, which are called out in
the text later in the exercise.
First, let's look at how the UVs are laid out for the A panel that you modeled in Chapter 6:
1. Using your scene or the scene file
RedWagonTexture_v01.ma
from the Scenes folder of
the RedWagon project, select the A panel on one side of the wagon, and choose
Window
➔
UV Texture Editor, as shown in Figure 7.71.
The UV Texture window works almost like any other view panel. You may navi-
gate the window and zoom in and out using the familiar Alt + mouse button
combinations.
2. RMB+click any part of the wireframe layout in the UV Texture Editor window, and
select UV to enter the UV selection. Select the entire wireframe mesh at lower right,
as shown in Figure 7.72. Notice that green points are selected—almost as if they were
vertices. These are UV points, and they're what define the UV coordinates on that
part of the mesh. Look in the Perspective view panel; the entire front face of the A
panel is selected as well the green UV points (also in Figure 7.72).
