Hi Andrew, When I do fading affects I have use osg::BlendColor in a StateSet that decorates the subgraph of interest.

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?
