@sera3D Hey buddy, read my post on this page with the leaves in it. N-gons are not your enemy. N-gons on uniform curved surfaces can be your enemy. On supported flat surfaces, N-gons flat out don't matter, and will enable you to save a bunch of modeling time and render-time by letting you end your supportloops in one e-z…
I believe that thinking in terms of how subdivison surfaces work fundamentally will help you both in this particular case and in the future, when you'll be facing similar issues. It helps me a lot to understand that, anyhow. Let's take a closer look at your geometry and try to think of what actually happens when you switch…
@IronLover64 To add to what's already been said: try to simplify the mesh by dissolving and merging some of the extra geometry. Straightening and rerouting the remaining loops into the existing geometry on the back strap should solve most of the smoothing issues. Flat surfaces that are properly supported are relatively…
