Hi Jeremy, It turns out that in the version I was using, osg-2.8.3 there are checks in osg::Geometry::drawImplementation() that would prevent the geometry being drawn when the traditional vertex position data is not present and generic attribute zero is not present. This is not the case for latest SVN and hopefully your version has the checks removed too. The context created by osg for me is 3.3 with backwards compatibility so standard attributes like gl_Vertex are present.
