  "With great difficulty" is one answer [grin]GI is still at the cutting edge of realtime graphics research and there is no general solution available like in the 'offline' world. All realtime approaches rely on some hacks or approximations.There was a good talk at GameFest this year on "Reflective Shadow Maps" that you might want to do some research into. Otherwise have a look at the "Spherical Harmonics / Pre-Computed Radiance Transfer" samples in the SDK.hthJack
