Faces
N-gons
Faces with more than four sides. They pinch when smoothed and triangulate unpredictably on export.

Polycop
One click reveals hidden n-gons, double extrusions, and non-manifold geometry in your model, with a live counter keeping track of all three as you work.

What it finds
Three problems
Points
Double extrudes
Extrude pressed twice without moving leaves squashed faces stacked on top of each other. Invisible in the viewport, obvious in a bevel.
Edges
Non-manifold
An edge shared by three or more faces, or pieces touching at a single corner. The kind of geometry that breaks booleans, bakes and game engines.
How it works
One button, two clicks
Select an object, a whole group or just some faces, then use the Polycop button on your shelf.
Click
Highlight every problem
Every visible piece you selected is checked, hidden pieces are skipped, and the problems are selected for you. The Script Editor lists the problem pieces, worst first. Press F8 afterwards to select just the problem pieces, ready for Isolate Select.
Polycop busted 12 pieces: 40 n-gons, 1 double extrude.
Ctrl + click
Keep a live count
Shows or hides a running total in the top-left of the viewport. It updates as you model, so a stray double extrude shows up the moment you make it.
N-gons 0 | Double extrudes 0 | Non-manifold 0

FAQ
Questions
Which Maya versions does it work with?
Maya 2023 or newer. It's tested on Maya 2024, 2025 and 2027.
Does it fix the problems for me?
No, and that's deliberate. Polycop shows you exactly where the problems are; how to fix each one is a modelling decision that should stay with you.
Will the live count slow Maya down?
On normal models it's instant. On very heavy meshes it counts less often, so Maya stays responsive.
Does it work on Mac or Linux?
Polycop is tested on Windows. Mac and Linux haven't been tested yet.
How do I uninstall it?
Right-click the Polycop button and choose Delete, then delete polycop_lite.py from your Maya scripts folder and polycop_lite.png from your Maya prefs/icons folder.
