My model is shaded smooth, and autosmoothed. But some edges/faces look sharp. How come? And how do I fix it?

  • $\begingroup$ it may be the artefact called Terminator Effect, since 2.9 you can easily fix it, just tweak the Shadow Terminator Offset value in the Properties panel > Object > Shading $\endgroup$ – moonboots Apr 15 at 5:39
  • $\begingroup$ Oh I see, so it brings the shadow line closer to the light source so the shadow covers the artifact and smooth shading is applied or something like that? $\endgroup$ – Jerry W Apr 15 at 23:42
