Of course, the material then mixes its color with the vertex color,
despite the fact that its transparent.
Try adding this to your global StateSet:
osg::LightModel *lm =new osg::LightModel();
lm->setColorControl(osg::LightModel::SEPARATE_SPECULAR_COLOR);
stateset->setAttributeAndModes(lm, osg::StateAttribute::ON);
I'm not sure if it'll work, but it's all I can think of...
