How to remove an island from a UV map? I unwrapped my head in one UV map and the unwrapped head still appears in the map when I create a new UV map. How do I remove the head island from my new map? Is sliding it out of the image the only solution? 

Here is an illustration of what I am requesting if it makes any sense.
To add a new UV map just clique the plus under Object Data Properties/UV Map.
To remove completely (deleting) a UV map just go to the minus icon. If you would like to switch between them just unchek the one ot the other.
