It did, indeed. Thank you. Anyways, the default OpenInventor viewer
seems to have a few "dark spots", when you happen to look from the wrong
point in the wrong direction.  I suggest one adds another SoPointLight
with, say, .5 intensity at 0,0,0. I could supply a patch, but the
changes are too trivial, and I dunno what is considered good "default
lighting".  Increasing the headlight intensity, by the way, doesnt cure
the problem.  Opposed to what one would think, the headline seems to not
rotate with the viewer ....

Just a remark.
Cheers

Wolfgang
