Managing UV Maps

After you finish editing a UV map, you may need to create additional maps on the same object, or transfer a UV map to another mesh.

Transferring UV Maps

You can copy a UV map from one mesh to another Mesh provided both meshes have the same geometry/vertex order. This is useful for example when you want to recreate a UV map from an earlier version of your model with intact UVs.

Workflow

1. Select the target mesh (to which you want to copy the UV map).
2. Shift select the source mesh (that contains the intact UV map).
3. Object menu ‣ Make Links… ‣ Transfer UV Layouts (Shortcut: Ctrl-L …).

The target Mesh will now have a UV map that matches the original mesh.

Multiple UV Maps

You are not limited to one UV map per mesh. You can have multiple UV maps for parts of the mesh by creating new UV maps. This can be done by clicking the Add button next to UV maps list (in Object Data tab in the Properties Editor) and unwrapping a different part of the mesh. UV maps always include the whole mesh.

UV Maps Panel

The UV Maps panel in the Mesh tab.

In the Mesh tab the UV maps panel contains a List view that lists the UV maps created for this mesh. The selected map is displayed in the UV Editor.

Active Render

Click the camera icon to enable that UV texture for rendering. If no other map is explicitly specified.

Add +

Clicking the Add button duplicates the selected UV map.

Note that each texture can be mapped to a specific UV layout.
