Issue with hemisphere part with textures

[Roland Melkert]

This makes the SPHERICAL mapping unsuitable for a full globe, which is unfortunate, but that seems to be what the specs say.
SPHERICAL mapping would be useful for smaller patches, e.g. an image on the surface of an old CRT television that has curved edges.

Many of these issues have been discussed before, e.g. my findings as posted here:

In short it is possible to do a full globe mapping but the mesh must be formatted to help it along, meaning it must have vertices at the poles and the texture meta must be oriented to match it.
