Hi Grafik, Nice to see your vision coming to fruition. I agree with everything Jim has suggested, except the idea that light cones dont go through transparent objects. They do. That and light sphere seem, in my experience, to be the only volumetric options that work with intervening objects. However, when using light cones, in this situation, you have to be mindful of the viewing angle. Certain viewing angles produce very unsatisfactory results. For example, try rendering your scene from different angles and at various distances. Anyway, almost straight on seems to work best when using some intervening transparent object. I don't know if the same is true without any kind of intervening objects.... Good Luck, .Painter
