I am modeling a tire. I used an array and a curve modifier to make my design wrap around in a circle.

General subdivided mesh

When I go to bevel and subdivide it, geometry on the corners of the high parts of the pattern curve very strangely to the underside and generate weird looking points.

Errors in the subdivided mesh Inside of the tires showing the wireframe and errors

I tried deleting the edges that cause the issue but it doesn't work because I cant't really put my finger on them.

This is the geometry I am trying to bevel after applying both the array and curve modifiers. Unsubdivided mesh and wireframe

Do you guys have any ideas on why this is happening/how to avoid it? Thanks in advance! :))

You could use this topology instead:

  • $\begingroup$ Thanks! @moonboots Are you suggesting I bevel the top first, then fix the topology and finally bevel the bottom? Or could I do that to the base mesh? $\endgroup$ Commented Sep 11 at 17:45
  • $\begingroup$ You could do several bevel at once, then change the topology to what I show, it really depends on what's best for you $\endgroup$ Commented Sep 11 at 17:55
