Now you people made me all stressed about N-gons

And I thought this looked so good…
Now I found N-gons. They’re not badass like klin-gons, either.

How do I get rid of them? How do I break those into separate triangles?
Is it because I removed all double vertices in my model? :frowning:

Never mind, nailed it! Selected and deleted just the faces of those n-Gons, so the bounding vertices (necessary for the other faces) can still exist and perform their function.
