Hi, I'd like to thank everyone for their suggestions so far. I've tried several different things, but none have worked.
Robert, I applied a BlendColor, but my model still appeared all white (flushed out from the light). When I applied the BlendColor with lighting off, my model did not fade in/out. I also received a recommendation from someone to apply a colored material to the billboard, because osg::Fade seems to operate on materials. Once I applied the material, my billboard retained the proper color, but it stopped fading in/out. Zach, I've attached the model to this email. I didn't include the fade node because that's not part of OSG. For some reason, the model isn't as flushed out in the stock osgViewer as it is in my app. As of now, I'm out of ideas and pretty confused as to why this is not working.
