The heart of the Edit UVWs dialog is a window that displays texture coordinates depicted as vertices, edges, and polygons, collectively called sub-objects. By default, these match the geometry of the mapped object; by editing the coordinates you change their positions in relationship to the object mesh. This gives you fine-grained control over how your texture maps "fit" your models.

The view window displays the UVWs in the 2D-image space of the map, superimposed over a grid. Thicker grid lines show the boundaries of a texture map as it would appear in image space; the lower-left corner of the rectangle has the coordinates (0,0) and the upper-right has the coordinates (1,1).

The state of the Edit UVWs dialog, including buttons and selected options, is stored and recalled the next time you open the Edit dialog.

NoteYou can edit patch object texture coordinates as well as mesh coordinates in the Edit UVWs dialog. When editing a patch object, you can also edit the vertex handles. In addition, you can edit the manual interior handles. However, you must enable the manual interior handles before applying the Unwrap UVW modifier. To do so, at the Patch sub-object level, select one or more patches, right-click a selected patch, and then, from the quad menu tools 1 quadrant, choose Manual Interior. The manual interior handles appear in the editor window as isolated vertices.
NoteCertain modeling operations can leave unused (isolated) map vertices that show up in the editor window, but cannot be used for mapping. If the model is an Editable Poly or Edit Poly object, you can use the Remove Unused Map Verts button at the Vertex sub-object level to automatically delete these vertices.
TipThe editor can display the number of selected sub-objects. This option is available as an Unwrap UVW shortcut as Show Subobject Counter.

Interface

Besides the window, the editor interface consists of a menu bar, three toolbars (one above and two below), and several rollouts on the right side.

Most of the tools available in the editor apply to selected sub-objects. To select UVW sub-objects, use the same methods and tools as when working with mesh sub-objects in the viewports. When dragging a region to select multiple sub-objects, only the rectangular region is available, but this method supports the active Window/Crossing selection toggle setting.

Menu bar

The menu bar provides access to a wide range of Edit UVWs functions. See Edit UVWs Dialog Menu Bar.

Toolbars and Rollouts

The editor toolbars and rollouts provide handy access to commonly used tools for working with texture coordinates.

Edit UVWs window

The Edit UVWs window allows you to edit UVW sub-objects to adjust the mapping on a model. For example, a texture map might contain the side, top, and front views of a car. By first planar mapping the top, side, and front faces of the model at the Polygon sub-object level, you can adjust the texture coordinates for each selection to fit the different parts of texture map to the corresponding areas on the car.

To edit the UVW vertices, first choose a transform tool and sub-object mode, make a selection, and then click and drag in the window to transform the selection.

Quad menu

Right-click in the window to display the quad menu, which provides access to all the transform tools, as well as a number of editor commands.

  • Edit UVWs Dialog Menu Bar

    The Edit UVWs dialog menu bar provides access to a number of important editing commands. Some of these commands are replicated on the dialog toolbar and the Unwrap UVW command panel; others, such as the Mapping, Stitch, and Sketch tools, are available only from the menus.

  • Edit UVWs Dialog Toolbars

    The Edit UVWs dialog contains three toolbars: one above the editing window and two below.

  • Edit UVWs Dialog Rollouts

    The Edit UVWs dialog contains a number of rollouts that provide various tools for editing texture coordinates. Among these are tools for transforming and subdividing UVWs procedurally, thus providing artists with useful shortcuts for more-efficient texture editing.

  • Unwrap UVW Shortcuts

    To use keyboard shortcuts for the Unwrap UVW modifier, the Keyboard Shortcut Override Toggle must be on.
