I have been trying to use the sunlight system to light some of my interiors, but if I have glass as my window, the light doesn't come in correctly and give me those nice shadows that the sunlight system gives you. If I make the glass a low opacity glossy material, they look correct, but my scene gets A LOT of fireflys. I have tried it with both the pathtracing and PMC kernels.

Does anyone know how to get this to work, or have any work arounds for using the sunlight system with interiors. Currently, I just remove the glass from the window, but this can look a little weird in some renders.

That seems to be how I have been doing it and using the glossy on the window ends up looking really nice, but it produces a lot of fireflys.
