Hi PaQ, so on your latest fillet cube example there, I notice that the artifacts are really pronounced in spots where there has been a centroid-style triangulation where the n-gon is triangluated with a center point added to it so the triangles are arranged in a kind of radial manner.

That also probably explains the difference that you saw between "triangles only" export and n-gons export in some cases, I forgot there can be different display triangulations used between those cases because the "triangles only" one gets those centroid points added when possible but the display triangulation for n-gons does not add them in and only connects triangles from the outer points of an n-gon.

You can disable the centroid style triangulation in moi.ini, under [Mesh Export], put:

[Mesh Export]
CentroidTriangulation=n


It looks like that could possibly shift the artifacts around a bit.
