When I use Subdivision surface modifier on that mesh, I can't see the mesh in my viewport. Any ideas or solutions to fix that?

Level 0 subdivided

Level 1 subdivided

  • $\begingroup$ I'd probably need to see a wireframe but my guess is that you're missing edges that would stop the mesh from collapsing. $\endgroup$ Feb 12 at 22:03
  • $\begingroup$ I suspect Haskell McRavin is right, and the fix for that would be to make sure you don't have Ngons. (the large C-shaped flat side, is it a single face ?) $\endgroup$

  • $\begingroup$ I've already read that, can't it be caused by the GPU Subdivision option in Preferences > Viewport > Subdivision? $\endgroup$
