Questions
Where do the rules come from?
From the stores’ own documentation: Roblox mesh and texture specifications, CGTrader’s quality checks, Unity Asset Store submission guidelines and Fab’s technical requirements. The model checking guide links each one.
Can it detect n-gons in GLB files?
No: glTF stores only triangles, so n-gons are already gone. In FBX and OBJ the tool reads the original polygons and counts faces with more than four corners.
Is a passed check a guarantee?
No. Stores also review by hand. The tool catches the automatic, measurable problems so a review is about your art, not about file names.
