Now we can move on to texturing the trailer arm and the hydraulic arm. Again, the method is the same. The only slight variation is the use of a cylindrical mapping technique for the hydraulic arm. (You may find that some of the cylinders already have cylinder mapping applied to them; these are usually created when you create the cylinder with “Generate mapping coordinates” checked. If this is the case, it just makes your life a little easier!) To map the hydraulic arm, move the end cylinder faces away from the main central cylinder, which makes it easier to select the middle so that you can apply cylindrical mapping to it. Also, move the two boxes and the end cap polygons away from the main cylinder. Once you have mapped the main cylinder, use the same technique on the end cylinders.

A good tip when using the cylindrical mapping technique is to try to hide the seam. For this example, the seam on the hydraulic arm is on the bottom of the model. The final step is to layout the polygons for the hydraulic arm. FIGURE 6.156
