Additionally, I'm using the setDefaults call for my SceneView and I'm
setting up a HEADLIGHT for the scene. This works well, but my main problem
is I scale the size of my planes and tanks as I soon in and out so they
appear the same size on the screen. Zooming out, thus scaling the planes and
tanks larger, causes the entity to appear unlit, or black. Is there a trick
around this?

Is it possible to take the lighting scheme from osgProducer::Viewer and
apply it to my own SceneView? I'm not happy with my current lighting
situation but for my specific purposes I need to roll with my own SceneView
instead of using the viewer. Admittedly, I don't know much if anything about
lighting. Whatever code I have is stuff I grabbed from the examples.
Specifically, I have a light over the top of my terrain but and that
lights it just fine, but my open flight models (tanks, planes, etc.) all
show up brightly and you can't see any contours on the model like you can in
osgProducer::Viewer. I'm guessing it probably has something to do with the
ambient lighting.
osg::BoundingBox bb;
bb.expandBy(bs);
osg::Light* myLight = new osg::Light;
myLight->setLightNum(0);
myLight->setPosition(osg::Vec4(bb.corner(4),1.0f));
myLight->setAmbient(osg::Vec4(1.0f,1.0f,1.0f,1.0f));
myLight->setDiffuse(osg::Vec4(1.0f,1.0f,1.0f,1.0f));
myLight->setDirection(osg::Vec3(1.0f,1.0f,-1.0f));
osg::LightSource* lightS1 = new osg::LightSource;
lightS1->setLight(myLight);
lightS1->setLocalStateSetModes(osg::StateAttribute::ON);
lightS1->setStateSetModes(*ss,osg::StateAttribute::ON);
group->addChild(lightS1);
Thanks,
Jason
