"From I think that this piece of code in StateSet::setTextureAttributeAndModes is a copy&paste mistake:
OSG_NOTICE<<"Warning: non texture attribute '"<<attribute->className()<<"' passed to setTextureAttributeAndModes(unit,attr,value), "<<std::endl;
OSG_NOTICE<<" assuming setAttributeAndModes(attr,value) instead."<<std::endl;
OSG_NOTICE<<" please change calling code to use appropriate call."<<std::endl;
setAttribute(attribute,value);
As per the warning message it should be calling setAttributeAndModes(attribute,value); ."
