Adding UVs to multiple objects

• same function can also be used for switching between maps

Copy Unique UVs

• easily find issues with naming and order

Functions:

1. Set Or Create Active Map for multiple objects

   • Sets a UV map active in each selected object. If a map with the same name doesn't exist, it'll be created automatically.

2. Delete Active Map for multiple objects

   • Deletes a UV channel with a matching name in all selected objects.

3. Set Active Render Map for multiple objects

   • Sets a UV channel as the active render channel in all selected objects.

4. Copy Unique

   • Copies all unique named channels in selection, to each selected object.

5. Sync Layers Order

   • Tries to match order of layers in each object to the active object.

6. Move Up / Down

   • Moves a layer in the selected object up or down in the stack, active object only, use sync order for other objects.

Initially I glued this addon together to make lightmapping complex scenes easier by avoiding manually setting the active layer for each object, it has since became an irreplaceable tool.
