NOTE If you have tumbled the camera for a different view of the orange or
the texture placement cube, ensure you reposition the camera so that the
oranges Mayakist logo is visible before rendering again. Otherwise, the
rendered image will appear incorrect.
In the rendered image, notice that the bumps still remain on the sphere.
Objects do not need to be within the texture placement cube, because it
represents an imaginary texture volume, which is infinite.
However, movement of the texture placement cube does shift the surface
texture pattern. The difference is hard to notice on a uniform texture like
Brownian. Transforming the cube would be more noticeable with a texture
such as Marble, where the veins within the pattern would be repositioned.
Movement of the object itself also shifts the surface texture. For example,
if you were to animate the orange rolling and then render an image
sequence, the texture would shift each frame rather than roll with the
surface. To prevent this undesirable effect, you need to make sure that
the texture moves in the same way the object moves. One way to do this
is to parent the texture placement cube (also called the place3dTexture
node) to the object. For more information on parenting, refer to the Maya
Help.
Beyond the lesson
In this lesson, you were introduced to some of the features available for shading
surfaces. You learned that:
Shading materials can employ a variety of material types that can be used
to achieve specific surface characteristics (Shininess, Matte, and so on).
