How to set an uv map, from an multiple uv, as primary one?

Question

Is it possible to set an uv map as primary one, in a multiple uv? For exsample I want that map02 becomes map00 (primary map). If it's possible, how to do that?

Answer 1

You can rename a UVMap in the UVMaps panel, either double-click or ⎈ Ctrl-click the name to edit it.

The little camera to the right of the name specifies the default map for blender, that is the one that is used if you do not select a specific UVMap.
