19. Notice how the image map is getting stretched and pinched in some areas. The checkerboard pattern helps us to easily identify these areas and clean up the UV coordinates so our final image map will wrap smoothly over our object. Since I know that the torso and shoe sections of the final map will be separate from the legs, I'm not going to focus on getting the grid to be consistent in size and edge connection across the entire object, but I will make sure for the 3 basic areas that the map lines up well and displays with a consistent size.
20. The inside of the leg looks very different from the outside. The grid pattern is much smaller for the inside. Since the inside of the leg is not going to be all that visible in the game engine, it's not overly important. Select all the polygons that make up the inside leg, and then using the size tool and move tool adjust the UV coordinates to better match the outside leg.
How To:
Use the "statistics" panel to select the "legInside" surface or use the "Lasso" tool, (right mouse button), and then size the polygons down using the "size" tool "H", in the "modify" tab. Once the size of the grid matches the outside leg, use the "Move" tool "t", found in the "Modify" tab, to adjust the inside leg's grid to align better with the outside leg.
21. The outside leg has some stretching and pinching in some areas, so using the move tool adjust the UV coordinate points to smooth out the texture.
How To:
Switch to point mode by clicking "points" in the bottom left or pressing "space" until it is highlighted. Click on the point in the "UV Texture" view you want to modify, and choose the "Move" tool "t" under the "Modify" tab. Drag the point, using the perspective view to judge the effects on the image map to find the proper position. Press "space" to drop the move tool, then Left Click on the select point again to deselect it. Select the next point you wish to modify and repeat the process.
22. Since the torso is a separate section as mentioned above, we will focus on smoothing the UV coordinates for just the front and back of the torso and not make a consistent connection with the grid of the leg section. The front torso only needs a little change to the bottom right point. The back needs a little more work to straighten out its lines, then move all the points to better line up with the front torso.
How To:
Follow the same guidelines as you did in step 20, "inside leg", for point adjustments to fix the torso.
23. The shoe needs a little more work then other areas. We have broken the shoe into 2 parts. The main part is the outside area, the section containing the laces and the entire area that connects the shoe to the sole. The other part of the foot is only the inside ankle. In some cases, it may be easier or more desirable to separate these parts further, especially the top of the shoe where the laces are, but for this instance we will be served fine with this simple distribution of UV coordinates.
Adjust the points to smooth the grid around the outside shoe surface. Pay special attention to getting a good transition on the top laces area. Now adjust the inside shoe surface to match the relative grid size of the outside shoe. Once the grid wraps consistently around both parts, make any final tweaks to the coordinates. As with the inside leg, the inside shoe surface is not going to be a prominent visible area of the character so perfection is not necessary.
