As you can see, not all of the north pole is rendering. Roughly 3/4 of the moon seems to have rendered, but it doesnt seem to have any of the red transition color in the north pole.
The moon model was made in Blender by simply creating a UV Sphere and then exporting it with triangulation enabled. No changes were made. The moon obj file can be found here in text version. Maybe the normals aren't correct? I tried using an ico sphere as well, but the results with that were even worse. Any advice for why it isn't rendering correctly?
