How can I duplicate a UV map on the same object? I want to have an object with two identical UV maps, but I don't know how to duplicate them. I feel like the answer is simple but I just can't figure it out.
When you add a new uvmap it will duplicate the selected uvmap.



If you want them to stay identical there is no advantage to having multiple uvmaps, the same map can be used for multiple image textures and in multiple materials.
