Maya – Using Multiple UV Sets

1. In the UV editor view, from the UV Sets menu, select UV Set Editor to open the UV Set Editor:
2. In the UV Set Editor, press the New button to create a new UV Set and double click it in the list to rename it:
3. Close the UV Sets Editor.

UV Sets allow you to create multiple arrangements of UV texture coordinates for a single surface. For more information, see UV sets. This section contains information on how to create and edit UV sets.

A UV Channel is a set of data within a Static Mesh that maps each of the mesh’s vertices to coordinates in 2D space. These mappings define how 2D texture maps get wrapped around the 3D geometry when the mesh is rendered.

The UV mapping process involves assigning pixels in the image to surface mappings on the polygon, usually done by “programmatically” copying a triangular piece of the image map and pasting it onto a triangle on the object.

What are UVs? UV mapping is the 3D modeling process of projecting a 2D image onto a 3D model’s surface. The term “UV” refers to the bidimensional (2D) nature of the process: the letters “U” and “V” denote the axes of the 2D texture because “X”, “Y” and “Z” are already used to denote the axes of the 3D model.

You know it as ultraviolet light, the wavelengths between 290nm and 380nm are (UVB/A) and 380nm to 500nm are (blue light). Because blue light has a very short wavelength, it produces a higher amount of energy than the other wavelengths of the visible spectrum.

Select the first group of faces, in this case the body, and choose “Copy UVs to UV set > Copy to New UV Set” option under the Polygons menu in the UV texture editor; call it Body. Now, you will notice a new UV set has been created which can be seen under the UV Sets menu in the UV texture editor.

Color options for shading can be found in View > Shaded. Identifies areas of stretching or compression by shading faces with squashed and stretched UVs. See Identify UV distortion. Toggles the display of texture borders on UV shells. Texture borders appear with a thick line. Toggles the display of colored UV borders to any selected components.

However, if you modify the default primitives in any way (that is, scale, extrude faces, insert or delete edges) you will need to map a new set of UV texture coordinates onto the object to suit your texture mapping requirements.

One of the most common uses of the UV Set Relationship Editor is to allow multiple maps for texture optimization. For instance, imagine this situation To get the largest possible texture to model ratio for my colour map I lay out my UVs like we see below.
