How to take away the wrinkles on the tentacles? so I have just started on blender 3D modelling and have a question regarding it. Now, I'm planning to create a 3D Octopus, and I'm stuck at the tentacle's suckers. After I shade smooth the tentacles, the tentacles appear to have wrinkles, how do I solve that?


I tried Knife tool too.
As it has been said, your topology is bad, the stretched triangles create these artifacts. To fix this, use the knife (K to activate, Z to cut through) to create new edge loops, and join (J) the vertices like that, and it should work:
