Thats what it looks like in max under the tri_fan primitive , as shown in this screenshot. Unless I'm on some kind of freak-mutant version of Max that no one else is experiencing. Try navigating around the sphere in 3D within Max, it should look like that 22 disk view.
I built the tri_fan2, quad_grid2 and tri_strip2 to mirror how things appear in Max, but there can be discrepancies. Play around until you get what you're after. If you want a solid object just use quad_grid or tri_grid , change the draw_mode from within Max , then set that as the same primitive on export and see if you're getting the results you expect.
