Hi Jody Add this code:
osg::ref_ptr<osg::Vec4Array> colors (new osg::Vec4Array()); colors->push_back (osg::Vec4 (0.0f, 1.0f, 0.0f, 1.0f)); colors->push_back (osg::Vec4 (0.0f, 1.0f, 0.0f, 1.0f)); colors->push_back (osg::Vec4 (0.0f, 1.0f, 0.0f, 1.0f)); geom->setColorArray (colors.get()); geom->setColorBinding (osg::Geometry::BIND_PER_VERTEX); Or use shader....
