Quick Planar Map gizmo superimposed over selected polygons You can toggle this feature and set the line thickness with the Display settings. This helps you visualize the locations of mapping clusters on the object surface. Each of these clusters has an outline called a map seam which appears superimposed over the object in the viewports. That way you can position the clusters precisely over different areas of the underlying texture map for optimal mapping accuracy. In using Unwrap UVW, you usually break up the object's texture coordinates into smaller groups known as clusters. You can animate UVW coordinates by turning on the Auto Key button and transforming the coordinates at different frames. In the latter case, you usually do so in order to use a mapping method unavailable in Unwrap UVW, such as Shrink Wrap.
You can use Unwrap UVW as a self-contained UVW mapping tool and texture-coordinate editor, or in conjunction with the UVW Map modifier. > Modifiers menu > UVs, Maps and Materials > Unwrap UVW Enhanced menu: Select one or more objects.> Modifiers menu > UV Coordinates > Unwrap UVW Standard menu: Select one or more objects.> Modify panel > Modifier List > Object-Space Modifiers > Unwrap UVW You can adjust mapping to fit on Mesh, Patch, Polygon, HSDS, and NURBS models using any combination of manual and several different procedural methods. You can also use it to unwrap and edit existing UVW coordinates on an object.
The Unwrap UVW modifier lets you assign mapping (texture) coordinates to objects and sub-object selections, and to edit those coordinates by hand as well as with a variety of tools.
