Ngon Scout

Highlights every n-gon (a face with more than four edges) across your scene so you can start the cleanup process — especially useful on n-gons buried inside a mesh.

This addon highlights n-gons (any face with more than four edges) so you can start the cleanup process. Especially useful for the n-gons hiding inside a mesh where you'd otherwise never spot them. An n-gon is a face or polygon made up of five or more sides/edges connected by five or more vertices — the topology mistake that breaks game-engine imports and subdivides ugly. Blender 3.0 – 3.6.
