The quickest way to create UV sets is while you map UVs. When you map UVs, open the options window, turn on Create New UV Set, and type a name in the UV Set Name box. For example, if you create two planar mappings, one from the top and one from the side, type a new UV set name each time you map.
Alternatively, you can start with an empty UV set and then create UVs.
To create an empty UV set
- Select the object, then select
UV > Create Empty UV Set >
.
- In the Create UV Set name box, type the name of the empty set and click Create.
- Select the new UV set (see Switch between UV sets).
- Create UVs with one of the mapping operations or by copying.
