First of all, you’re right about the fact that there’s no hole in the surface under studs, and this technically results in incorrect rendering. However, it’s not something that people notice. Additionally, the missing hole under studs is fundamentally different from two co-planar overlapping polygons. My understanding was that this thread was about co-planar overlapping polygons. The rendering problems they introduce are much more likely to be noticed than polygons which extend across places that should have holes.

   It is necessary to make the difference with an excessive overlapping (bad use of primitive and quad) and a necessary overlapping for the check returned by the part.

I personally would say that, in general, co-planar polygons shouldn’t overlap. But that’s just my personal opinion.
