Reply To: Question on “sharp” vertices, example at 11:16 in the video

HI Dano @dwillies ,

My guess is, that you have ‘double Vertices’, and/or inconsistent Normals.

(A, to Select ‘All’, M > Merge > By Distance, followed by SHIFT+N; this solves more than 90% of al your modeling problems.)

Could of course be something else, but I can’t tell much from this screenshot.
