- Layout rectangle
-
Creates an evenly distributed UV rectangle from a selection of two vertices. The selected verties define the top left (0,1) and bottom right (1,0) corners of a rectangular patch of geometry. The UVs contained in the selection area are laid out evently starting at the top left corner and ending at the bottom right corner.

-
Rotates the U and V values of the selected polygon. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Best Plane Texturing Tool
-
Assigns UVs to the faces you select based on a plane computed from vertices you specify. See Create UVs > Best Plane Texturing Tool.
- Grid
-
Moves every selected UV to its nearest grid intersection in texture space. See Edit UVs > Grid. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Align
-
Aligns the positions of the selected UVs. See Edit UVs > Align. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Warp Image
-
Modifies a texture image by comparing two UV sets on a single polygonal mesh and produces a new bitmap image. See Edit UVs > Warp Image.
- Map UV Border
-
Moves UV borders to the edges of 0 to +1 texture space. See Edit UVs > Map UV Border.
- Straighten UV Border
-
Untangles the border of a UV texture shell, such as an edge that loops around itself. See Edit UVs > Straighten UV Border.
- Optimize
-
Spreads out all UVs to make them easier to work with. See Edit UVs > Optimize.
- Unfold
-
Lets you unwrap the UV mesh for a polygonal object, and attempts to prevent you from creating overlapping UVs. See Edit UVs > Unfold.
- Layout
-
Attempts to rearrange the UV shells into a cleaner layout, based on the settings in the Layout UVs option box. See Edit UVs > Layout. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Cut UV Edges
-
Separates UVs along the selected edges, creating borders. See Edit UVs > Cut UV Edges.
- Split UVs
-
Separates UVs from each other along the edges connected to the selected UV points, creating borders. Shortcut for the texture editor’s Edit UVs > Split UVs. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Create UV Shell
-
Converts the currently selected components (vertices, UVs, edges, or faces) to a line of edges around the perimeter of your selection, and then makes a cut along the perimeter, creating a new UV shell. See Create UV shells.
- Sew UV Edges
-
Attaches UVs along the selected borders, but does not move them together in the texture editor view. See Edit UVs > Sew UV Edges. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Move and Sew UV Edges
-
Attaches UVs along the selected borders, and moves them together in the texture editor view. See Edit UVs > Move and Sew UV Edges. This item is also found on the UV Texture Editor toolbar for quick access. See UV Texture Editor toolbar.
- Merge UVs
-
Merges together separate UV shells. See Edit UVs > Merge UVs.
- Delete UVs
-
Removes the selected UVs from the mesh. You will need to re-map or re-project the UVs in order to map textures onto the affected areas. See Edit UVs > Delete UVs.
- UV Snapshot
-
Saves an image file of the current UV layout. You can then paint on this image in a painting program or use this image as a background reference layer for texture work in an image editor such as Adobe® Photoshop®. See Save an image of the UV layout. An option window appears with the following controls:
- File Name
-
You can save the file anywhere inside or outside of your project. Maya automatically assigns the file extension based on the image format you select.
- Size X, Size Y
-
Sets the dimensions of the exported image. Use the same dimensions you want for the file texture you are about to create. If you are not sure, use the default size; you can scale the exported image later in your paint program.
- Keep Aspect Ratio
-
The aspect ratio is the ratio of Size X to Size Y. With it turned on, you can change one size slider and Maya automatically adjusts the other size value to keep the same ratio. If you need to change the aspect ratio, turn off this option temporarily and adjust one of the sizes.
- Color Value
-
Sets the color of the UV patches in the exported image. The background of the snapshot is black; therefore, the Color Value should be white or another contrasting color. You can click the box to open the Color Chooser.
- Anti-alias Lines
-
Controls whether lines in the output image have anti-aliasing.
- Image Format
-
Use an image format that your paint program can read. If you require an alpha channel while painting, use TIFF or a similar format.
- UV Range
-
Normal (0 to 1) specifies the range between 0 and 1. When this option is set (default), only the UVs appearing in the 0 to 1 area are included in the 2D image that gets output.
Entire Range specifies that a 2D image will be output that covers all displayed UVs regardless of their position within UV space. That is, if the UVs lie outside the 0 to 1 range, they will still be included in the UV snapshot image.
User Specified allows you to customize the UV range that will be output by specifying minimum and maximum values for U and V. This is useful when you need to output an image of a specific UV shell or a specific region within the UV Texture Editor.
