Thanks John. I'll give it a try. So I assume that this overrides the osgViewer default light settings?
Thanks again for the help... -Shayne -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Argentieri, John-P63223 Sent: Tuesday, June 10, 2008 4:36 PM To: [EMAIL PROTECTED] Subject: Re: [osg-users] lighting in osgViewer... Shayne, If you really want to control lighting, you have to use osg::Light and osg::LightSource. If you look at the code for the example "osglight" you will see how those types of lights are set up. Say for instance, you want a constant, non-directional light. Copy the "osglight" example, but instead of what they do with the osg::Light, do: m_Light = new osg::Light(); m_Light->setLightNum( 0 ); // this will override the "Look at me, I am the sun" light. m_Light->setAmbient( osg::Vec4f( 1.0f, 1.0f, 1.0f, 1.0f ) ); m_Light->setDiffuse( osg::Vec4f( 0.0f, 0.0f, 0.0f, 0.0f ) ); and you don't have to worry about where it's located because it has 0 directional lighting.

This may be a silly question but can anyone enlighten me on what osgViewer::setLight() does? Does it set the attributes for a global light source in the scene? I want to change the defaults in the viewer. Thanks in advance -Shayne
