Can't get rid of sharp edges

I have no idea what happened, but I hit undo while working on some UV layout and suddenly all these sharp edges showed up on my model. And I can’t seem to get rid of them. Smooth shade and clear sharp seem to do nothing. The model was behaving normally before… is this a bug?

Could be a bug. What version are you using?

Is the mesh perhaps set to Auto Smooth?

You’re my hero. It was auto smooth. I didn’t even know that was a thing that existed. Must have hit a shortcut for it by accident or something…? I dunno…

Thanks for the help!

You’re welcome! :+1:
