Okay, so where I locate the sphere as I put the image map on it makes a
difference... That could be the source of the "inconsistencies" I was
seeing. Especially between identical spheres placed in different locations.
And it did seem like moving the spheres had an effect on the image map.

As you suggested, I will try creating them at <0,0,0> first and then moving
them to where I need them.

Thank you for the code examples and the documentation locations.
