Hi Robert, Yes I used OSG itself and can switch off the lighting, but then I can’t use OpenGL to switch on the lighting from exterior…… Does the OSG only use itself to control lighting? Is there any other way to use OpenGL code to control OSG lighting on and off?

Something like: node->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF); Robert. -------------------------- --wangzhu 2007-07-11
