Just throwing out ideas -- what about using a fade LOD technique? I know it
temporarily incurs a higher draw overhead of drawing a tile at two
different LODs at the same time, but perhaps it would be worthwhile in your

OpenGL FFP lights are point light sources only.
Generally you have to simulate non-point light sources with arrays of
lights (FFP) or a custom shader (GLSL). No examples of either of these are
included in OSG.
