Unlike OpenGL, OSG's Material class wraps both the glMaterial and glColorMaterial features. Color Material redirects OpenGL to pick up material lighting parameters from the primary color. So, you just need to configure the OSG Material class to use Color Material, then lighting will use the vertex colors. -Paul
