  • I have a shape I created from a cylinder.
  • It's wider at the top.
  • I have a bevel modifier applied.
  • I have subdivision modifier applied.

I am trying to extrude incomplete ring of faces along normals, like this: enter image description here

With the modifiers, this results in artifacts around the corners and gaps, where the extruded part doesn't look attached to the part below it: enter image description here

enter image description here

What would be the best way to deal with this? I have tried a few things like beveling the edge connecting the shapes, separating the mesh, adding ring loops... with no luck.

Here is the file:

Thanks!

You can use this kind of topology, but I've added vertical edge loops on this part (like if it was a 32 vertices cylinder) in order to avoid bad shading:

  • $\begingroup$ Hi! thank you for the answer! Could you elaborate a bit? It looks like you beveled the edges maybe? $\endgroup$

  • $\begingroup$ Yes and once you've bevelled you need to create the topology I show in the second picture. Maybe use a Shrinkwrap on some of a vertices with a cylinder as target and your vertices as vertex group so that your vertices keep a nice round shape $\endgroup$

  • $\begingroup$ Thanks. I've been messing around with it and i guess i don't know enough yet to be able to replicate this yet. Will accept if I don't get other suggestions $\endgroup$

  • $\begingroup$ Nevermind, i watched a bunch of videos on redirecting edge flow and was able to do this. Thanks! $\endgroup$

  • $\begingroup$ oh ok great, sorry for not being more helpful, it's a bit complicated to explain the whole thing in Blender Stack Exchange, you're right videos are much better to understand $\endgroup$
