UV Top Bar

There are a number of functions to view, create and edit UV Maps. Let’s look at each of these components.

Located near the top of the interface is the Top Bar; this panel includes the functions needed to select every type of component from your UV Map (vertices, edges, polygons & islands) for manipulation with the UV gizmo.

This panel also displays which UV Tool you are currently using, which type of default texture you wish to show mapped onto your Unwrapped Retopo Object (simple checker, etc.), and a drop-down menu that shows a list of UV Maps that you have produced for that mesh.
It will display all UV Maps, whether created in another application, imported with the mesh, or created within 3DCoat.

These options are:

The UV Map drop-down list also has functions to Add, Delete and Rename UV Maps (UV Tiles).

Move Selected is a drop-down list with all the existing UV Maps that will let you move selected components to another UV Map by selecting that map in the drop-down.

They are Import/Export UV, which allows you to import/export the mesh with the current in-progress UV editing from the UV Room to/from disk.
