There's no reason to warn about such a situation. The "hollow" keyword 
only affects how the object interacts with media.

BTW, instead of a huge sphere you could just as well use a sky_sphere - 
it /should/ do exactly the same (provided you're using "#version 3.7"). 
There /is/ a difference between specifying a background and specifying a 
single-colored sky sphere.
