send me that, im going to code that whether you like it or not.DTS and Materials pls
It don't think the are any major ngons in the model and even if there were they wouldn't be that noticeable.
On the outer ring of the one on the left you can clearly see the edges of the "circle". Although I suppose the right terms would be the three-dimensional counterparts of a circular ring and an n-gon in the shape of a ring.
EDIT:
That is a nice render what did you use?
You can see the edges because the left one is lower poly. Still no need for ngons:-snip-Add a subdivision modifier:-snip-Using ngons for the ring would break the edge flow which is exactly the opposite of what you want especially in a ring shaped structure. Using quads is far more practical.
Obviously n-gon has a silly modeling connotation because I meant the shape traced by the top layer of outside vertices. Which in mathematics would be an n-gon.
From left to right: A triangle "tri", a square "quad", an octagon "8-gon" (single face!), and an octagon constructed of 3 quads.
Blender
An octagonal face is called an 8-gon because it has one, two, three, four, five, six, seven, eight glorious sides and one, two, three, four, five, six, seven, eight stunning angles
