- How can I deactivate the lighting set by default by the osgViewer ?
The fact that osgViewer/SceneView set up default lighting does seem to confuse many users, as your posting demonstrates. However, lighting state is really no different from any other state. You can control it in your own scene graph using standard OSG setMode, setAttribute, and setAttributeAndModes calls. StateSet::setMode( GL_LIGHTING, OFF ); // Disable the OpenGL lighting feature StateSet::setMode( GL_LIGHT_0, OFF ); // Disable OpenGL light 0 The above two calls disable the two features enabled in osgViewer/SceneView by default. If you want to leave lighting and light 0 enabled and simply control the light's attribute (position, color, etc) then you should use osg::Light and the osg::LightSource node as demonstrated in the osglighting example program.
