Try osgconv --smooth yourBillboardedModel.osg new.osg This should fix any normals that are in your model, and for the billboards to be lit correctly. Of course, you'll have to turn GL_LIGHTING back on for the model.
I remember doing the same thing with osg::Fade. Maybe someday one of us will integrate it into the main codeline, and get fade-lods for everybody?

Sent: Tuesday, March 13, 2007 17:14 To: osg users Subject: [osg-users] osg::Fade and Lighting Problem Hi, I have an OSG-based application with several billboards that contain rectangular geometry. I made the billboards children of LOD nodes so that they disappear at a certain distance. I wanted to create a fade effect, so I downloaded Don's osg::Fade class from http://www.andesengineering.com/misc/fade.tar.gz. This class seems to use lighting in order to fade objects in and out. My problem is that I had GL_LIGHTING turned off for the billboards. I did this because when lighting is on, they show no color (they appear all white from the light). Unfortunately, the fade in/out will not work when GL_LIGHTING is off. Does anyone know how I can retain the billboard's color without turning off lighting?
