Hi Sherman -- Interesting issue.
OpenGL is a state machine, and if you're just using raw OpenGL, then you
could enable blending, for example, never change blending state again, and
blending would
Is strange. I'm using all OSG code. Is possible I've found some odd
OSG bug - but I think is more likely that I'm doing something that's
not intended and am experiencing a side effect. I'm going to spend a
bit of time and see if I can simplify this problem down to a trivial
example.

Paul - thanks for the suggestions. I've found an older code tree of
mine from November 07 and everything seemed to work there. I'm
investigating.

I'm overriding the traverse function. It is written in such a
way that the CULL_VISITOR doesn't have an opportunity to call
osg::Group::traverse(nv). When I add this object to the
scenegraph all the nodes in my scene go black.
I've found a few clues this evening. Not sure why things are behaving
the way they are - I'm probably abusing the OSG in my overridden
traverse(...) function. My node has a shader attached. If I do NOT
attach that shader to the stateset, no problems. Read on
