Hi, FlightGear now includes a deferred renderer that produce shadows. As the lighting is done from a Gbuffer in a fullscreen quad render, I can't (correct me if I'm wrong) use osgShadow.
So in my implementation, I render the geometry of the whole scenegraph to a depth texture using an orthographic projection in the direction of the light. The view matrix sets the sun position at 10000m from a position ahead of the viewer. But when the viewer is near an object that has a LOD node that has a range of 0 - 9000m, the model is not renderer in the shadow map and the viewer doesn't see a shadow. So the question : is there special code in osgShadow that address this kind of situation : a LOD range for the viewer unsuitable for the light source ? I tried to override the LOD::traverse method in a specific cull visitor that calls Group::traverse instead, but I was said it is a bad thing, and I can understand it breaks PagedLOD and any descendant too.
