How do you select an entire UV island on a mesh by selecting a piece of the desired island? Similar to the Ctrl+L for selecting all connecting geometry, only selecting all geometry within seams.

I.E. select a vertex within an island.

And hit some hot-key to extend the selection to the marked seams.

I use this feature all the time in 3ds Max, so I can unwrap a piece at a time. It would be a huge timesaver to be able to do this in Blender as well.

  • $\begingroup$ That's odd.. The select linked operator has a limit by seams option in the redo panel (F6), but it doesn't seem to work? Might be a bug. $\endgroup$

  • $\begingroup$ Limit by seams only works in face-select mode (note, Blender should really be changed to report a warning if used in vert/edge mode) $\endgroup$

    $\begingroup$ I mean there should be, as in - We should add one!, Will try resolve these issues (and make some other planned improvements) to select linked in the next week or 2. $\endgroup$

To select an entire island within seam boundaries: In edit mode activate FACE SELECT, hover the mouse over the wanted island, and press L.

Not exactly what you are asking for, but hopefully helpful.


Update, UV islands in Vert/Edge/Face modes has been added

In the operator options, enable UV as a delimiter to select UV islands:

  • Select a vertex/edge/face.
  • Press Ctrl+LKey.
  • Enable UV option in toolbar.

Previous answer (Versions 2.74 or older)

Select linked can delimit by seams, but this only works in face-select mode *:

  • Switch to face select mode
  • Press LKey over the region, the selection will be restricted to the seams.

If you don't have seams around the UV island, you can automatically create them.

  • Image Window, UV -> Seams from Islands

* - this is intentional, select-linked traverses only faces in face-select mode, and edges in vert/edge mode.
