You can do this by selecting the face and using Select > Select Split from the Image Editor header or the Y key, then drag to separate. This method doesn't require you changing the Sticky Selection Mode, but it does require that you separate at least one tri. This method does not work for separating a single point or edge.

  • Any idea how to do this in blender 2.8.x? – Pieter De Bie May 28 '19 at 05:24
  • @PieterDeBie I couldn't find a menu entry for it but the same shortcut seems to work. Open the context menu with space and search for Select Split. After running the operation, press G and move the cursor. – iKlsR May 28 '19 at 12:58
  • "This method does not work for separating a single point or edge." Wait, so you can't cut a single UV edge in Blender? Is that what you're saying? Guess I'll just go back to importing/exporting between Maya for what should be a most basic and straightforward operation. – arkon Jul 22 '22 at 16:10

Change the Sticky Selection Mode to Disabled in the bottom settings bar, then drag to separate the selection.

  • This function behaves oddly, it seems you have to select it again even though it is already selected by default. – iKlsR Oct 13 '13 at 03:01
  • @iKlsR - this is working as intended, changing sticky mode wont change the existing selection, only new selection actions – ideasman42 Oct 13 '13 at 05:50
  • @ideasman42 as it turns out, I was doing multiple tests with the same map, so it was on my end. – iKlsR Oct 13 '13 at 05:55
