By default, the Texture Placement tool is set for Label Mapping, which lets you stretch, shrink, move, and rotate the texture as if it were a label. You can change set the tool for Surface Placement, which lets you stretch, shrink, move, and rotate the texture as if it were wallpaper.
In both cases, wrap U and wrap V control the tiling of the texture in horizontal and vertical directions (based on the UV coordinates on the object).
To change the Texture Placement Tool, double-click the Texture Placement Tool icon in the toolbar, or select Texturing > NURBS Texture Placement Tool > See Texturing menu for more information..
