I have caught myself adding sharps instead of seams during this exercise a few times, so that may be it. Another newbie thing I learned (in case it helps someone else) is I thought it wasn’t letting me add seams/sharps, but it was adding them and just I had the view turned off in the Overlay settings. It turns out the Overlay settings are unique to each workspace. So for example, if you enable or disable the overlay View Seams setting in the Layout or Modeling workspace, and move to the UV Editing workspace the settings apparently aren’t shared between the workspaces. It took me an embarrassingly long time to figure that out! This Treasure Chest tutorial is great and I’ve already learned so much from it – thank you Kent & CG Cookie for sharing your talent with us and for all that you do!!!
