UVWs straight and even. If your UVWs are laid out improp-
erly, then the checker pattern will be flawed, as shown in
Figure 17-10.

Serious stretch-
ing in the UVWs
Our checker pattern looks good, but what if we wanted to
modify our cube a bit? Let's adjust the width of the cube.
Note:
Any standard primitive will automatically generate its own
UV coordinates if you have the Generate Mapping Coords
box checked when you create it. That is why our checker
material is showing up properly. Of course, if we were to
modify the cube, then it would start to break down our
UVWs.
Scale the cube roughly 500% on the x-axis in your Perspective
view. As you can see, the Checker texture starts to stretch
out. If we were using a texture like cardboard, this would com-
pletely break the illusion of the box being made of cardboard.
