I'm trying to make a Flight Sim with very accurate instrumentation data (specifically location, rotation, velocities, etc) using Blender and Armory3D. To do this, I'd like to have the user's plane fly around an elliptical Earth of roughly the same size and shape.
However, when I create a 6378.1370 km by 6356.7523 km ellipse and set the z offset to -6356.7523 km, the object disappears. At that point, the top of the ellipse should be touching the world origin and should be in view, but I can't see it. Why is that?
