Why do shaded smooth faces have weird shading. Face orientation is as it should be I did check that.

4 faces have really weird shading that sticks out from the rest

  • $\begingroup$ check if you have custom split normals in the data properties panel $\endgroup$

You have several duplicate vertices on your model. In Edit mode. hit A to select All then M > Merge by Distance.

You'll briefly see a message in the bottom status bar saying that 16 vertices have been removed and your topology will then be correct.

  • $\begingroup$ Thanks man, worked like a charm, and yes thank you for pointing out the crotch area, I didn´t put clipping in the mirror modifier. That being said, I have been looking at this overlap in the arm and shoulders you mentioned and can´t see it at all, even in wireframe mode and looking inside the model. If it doesn't trouble you too much, would you be able to clarify on this overlap? $\endgroup$ Commented Aug 16, 2023 at 11:18
  • $\begingroup$ If you just use Alt-Z for x-ray mode and Ctrl-3 on the numpad for side view, you can see that there's one vertex in the middle of the shoulder area which is a lot higher than the others. Select it and change to front view and move it down and outwards to improve the topology a bit which should help with the shading. There's also one vertex at the heel of the feet which doesn't seem to be in the correct place! :^) $\endgroup$
