Hi, Considering I've created an osg::Material this way, and that the nodes are shown on screen :
Code: m_material_selected = new osg::Material(); m_material_selected->setDiffuse(osg::Material::FRONT_AND_BACK, osg::Vec4f(0.2f, 0.2f, 0.75f, 0.5f)); m_material_selected->setSpecular(osg::Material::FRONT_AND_BACK, osg::Vec4f(0.2f, 0.2f, 0.75f, 0.5f)); m_material_selected->setShininess(osg::Material::FRONT_AND_BACK, 75.0); m_material_selected->setColorMode(osg::Material::AMBIENT); And then I set it to a node like this ( this is apparently working so far ... ) : Code: // Where node_sel is a previously created osg::Node* node_sel->getOrCreateStateSet()->setAttribute(m_material_selected, osg::StateAttribute::ON | osg::StateAttribute::OVERRIDE); But when I try to remove this attribute from the previously created node like this : Code: // Where node_unsel = node_sel; node_unsel->getOrCreateStateSet()->removeAttribute(m_material_selected); My app crashes. What did I do wrong ? Is it unsafe to removeAttribute from a node this way ? I've seen on the forum things like NodeVisitor class, should I be using this or can I change nodes manually ? Thank you for your interest in my question, Have a good day, Paul ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=72479#72479 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
