Well I don't think it's because of the include files, as most of us are
using v3.7 release candidate versions now with those very same include
files. In 3.7 the #version directive in those includes handle them
properly. I'm running a rather lengthy render now and I'm not inclined
to stop it to test your scene, but my 1st guess is the dark-ish colors
that you are using ... gives little contrast between the background and
your test object. Try moving the light source to the left or right just
a tad, so you can cast a shadow someplace other than just behind the
test object. Also explore the finish attributes, diffuse, specular ....
etc. Casual glance at your scene source indeed looks fine. Play around a
bit with the issues I've mentioned and see if it makes a diff .... shout
if you need help. Also post an image in the appropriate news group to
give us a look at what's going on. This is a pretty good group and most
of us like lending a hand.
