The text calls this the first tutorial chapter. It has several lengthy tutorials for textures used in a "science fiction" scene. In my opinion, it could just as well be a waste treatment scene from Dirty Jobs. Regardless, let's take this as an art assignment. The author asks some reasonable questions on page 184, regarding the age, use, and materials used to make the "real" structure that we will be making textures for. Does that matter? Yes, it does. Whether we are texturing for a movie, a video game, or something else, we want to make the textures match the characteristics of the scene.
The author explains his plan to make several textures that can be combined and reused in the scene. The concept art shown on pages 182 and 183 is blurry and vague, but the descriptions of it on the following pages should be taken as specifications to the artist about what is needed for the scene. The author develops a list of required texture elements on page 185:
This is what makes a realistic job assignment: requirements from an authority that must be met (a director, art director, lead designer, or someone else in charge). Without knowing what must be done, it is impossible to complete an assignment. You may be as creative as any artist the world, but if you do not get the design goals and requirements at the outset, you will will be wasting your creativity and your time.
For each tutorial you do, you must show me your texture file for grading.

New assignment: The remaining tutorials are missing several pieces of information. We will continue with an alternate assignment.
