to complement the question, I am asking myself if the code in SceneView::cullStage line 972 of SceneView.cpp (v3.0.1) that reads : cullVisitor->pushModelViewMatrix(mv.get(),osg::Transform::ABSOLUTE_RF); is right. It seems to ignore the reference frame settings of the slave camera and assume ABSOLUTE_RF. Should I manually set the viewpoint of my main shadow camera ? and how ?
