Right All seven of the mapped groups are placed directly on top of each other. layered you must use Isolate Select mode to be able to work with any particular group on its own. Using the Isolate Select mode is relatively easy. Follow these steps 1. Select the UVs of the group that you want to work with and click the Add Selected icon on the Texture Editor toolbar as shown in Figure 2.6. 2. Click the Toggle Isolate Select Mode button. Now all of the other UVs should disappear leaving only the group that you added to the set. 3. Make any necessary adjustments to the UV group select all the UVs and click Remove Selected to empty the Isolate Select mode. 4. Toggle the Isolate Select mode off. Eventually a different file texture will be applied to the faces of each grouping. Layering the UVs for the human model allows for much more detail since 7 to 10 textures as opposed to 1 or 2 are applied to one figure. You can apply one giant texture to a model and achieve similar results without layering UVs but pen-and-ink drawing techniques are limited in how thin a line they can produce. Thus for the scale of the texture drawings to remain the same size a large scanner would be necessary or a patchwork of multiple scans. Both methods present a multitude of their own problems. In the mapping stage plan out seams on the model s texture that are naturally produced by separate pieces in the Texture Editor. By strategically adjusting the UVs so that seams fall where a drawn line will occur see Figure 2.7 any seam will be virtually invisible. It is not always possible to create seams where lines would naturally fall however so other seams are manipulated to manifest in hidden or seldom seen areas like on the back or under the arms of a character.
