Integral(L * cos(thetaN)) * Integral(V * cos(thetaN))


Unless I'm mistaken though I thought that would not give the same result as Integral(L * V * cos(thetaN)). Should have kept reading because you go on to say as much. I was hoping there would be a way to "correctly" modulate irradiance from an irradiance volume using something like a H basis encoded occlusion map.
