UV Texture Editor reference
The UV Texture Editor ( Window > UV Texture Editor or Edit UVs > UV Texture Editor) lets you view and interactively edit UV texture coordinates for polygons and subdivision surfaces.
You can select, move, scale, and generally modify the UV topology for a surface very much like you work with other modeling tools within Maya. You can also view the image associated with the assigned texture map as a backdrop within the UV Texture Editor and modify the UV layout to match as required.
Items in the UV Texture Editor can be selected from either the menu bar or from the graphical toolbar. For more information on the UV Texture Editor options see:
