Locating the dreaded N-Gon
So, I've learned that n-gons are bad and that quads are good (agree or disagree?). I've also heard that triangles, albeit not as bad as the dreaded n-gon, are not preferred either.
My current side project features a low-poly van as the centerpiece, and it's looking pretty good. However, I'm finding n-gons peppered throughout the mesh. What can I say? It happens.
I've heard that a sure fire method of finding n-gons is to insert an edge loop. If the mesh won't accept an edge loop, then you have a poly with more than 4 vertices. So, I've been doing that regularly, but I find that it works sort of one face at a time, if that makes sense. It doesn't find all the n-gons.
So, I discovered a new method that I thought I'd share that seems to work pretty darn well. Now, you experts out there may scoff at this method, or share a faster way using one of those fancy five fingered hotkey combos. Others, however, may find this process very useful.
- Select your Object and tab into Edit mode.
- Go into Face mode vs. Edge or Vertex mode, or press 3.
- Click the Select tab.
- Scroll down to Select by Trait and click Faces by Sides.
- If you don't see the elusive little tool properties menu that likes to appear and disappear like a Ninja, press T to toggle the tool properties menu
- Set the value for Number of Vertices to 4
- For Type, changed it to Greater Than.
The result was an instant selection, highlighting all the n-gons in my mesh (see image below).
For me personally, I think this is a very useful tip, and I hope you will find it useful too!
Thanks in advance for your comments and suggestions.
